The Co2 laserwas one of the earliest gas lasers to be developed. It was invented by kumar patel of bell labs in 1964 and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available. They are also quite efficient: The ratio of output power to pump power can be as large as 20%. The co2 laser produces a beam of infrared light with the principal wavelength bands centering on 9.6 and 10.6 micrometers (μm).Series co2 laser provides more than 50 watts at 10.6um with the most compact size, making it a good solution cost-effective for laser marking, engraving, and cutting systems where performance and reliability in industrial environments are essential.

Types of CO2 Laser
Longitudinal flow and transverse flow lasers
These are the simplest designs and are mostly used with high power output lasers. In these lasers laser gas is continuously vacuumed through a discharge tube by means of a vacuum pump.
Sealed off laser
These are lasers that have a glass tube filled with the co2-n2-he mixture. Hydrogen, water vapor and oxygen are added to the gas mixture instead of the gas mixture being replaced by the pump. This is because an electrical discharge quickly breaks down co2, generally in a few minutes, hydrogen or water vapor is added to react with the carbon monoxide and oxygen to reform the co2.Co2 is therefore catalytically regenerated.
Waveguide laser
This type of laser is formed when the sealed tube is replaced by a waveguide, with an inner diameter of a few millimeters. It is also known as the slab laser. The lasing volume of the waveguide laser is less and thus it produces a smaller power output. It has a resonator that has a relatively large surface area compared to the volume. This allows efficient removal of heat loss. The resonator is cuboidal in shape.
Transversely excited atmospheric pressure laser
This design uses a discharge voltage which is applied in short pulses of under one microsecond across the gas flow. This method prevents arcing. This design is used when high pressures are required. Since the required voltage for a longitudinal discharge is too high, transverse excitation occurs with electrodes that are in series along the tube.
High power diffusion-cooled slab lasers
These types of carbon dioxide lasers have their gas in a gap that is between a pair of planar rf electrodes that are water cooled. Diffusion is used for the transfer of excess heat to the electrodes, if there is a small spacing of the electrodes compared to the width of the electrodes.
Gas dynamic carbon dioxide lasers
These types are a kind of chemical lasers for multi-megawatt powers for example anti-missile weapons, where there is no provision of the energy by a discharge of gas but by a chemical reaction.
Carbon dioxide lasers vs. Solid state lasers
Carbon dioxide lasers that are used for the processing of laser material (such as cutting and welding of metals or laser marking) are in competition with solid-state lasers (particularly fiber lasers and yag lasers) that operate in the 1 micrometer wavelength. These shorter wavelengths offer advantages that include more efficient absorption in a workpiece that is metallic and the potential for delivery of beam via fiber cables.
In a gas mixture of carbon dioxide, nitrogen and helium, which serves as an active medium, electromagnetic waves in the megahertz area are broadcast. The carbon dioxide molecules are stimulated and brought to a high level of energy. The energy is stored in these molecules as vibration or rotation. A continuously emitting carbon dioxide laser can be stimulated with a high voltage up to 20,000 volts and the resulting glow discharge. The stimulation of the molecules is possible with a high DC voltage or high-frequency change voltage.
The carbon dioxide molecules have different forms of vibration with different energy levels. If an infrared photo meets an excited carbon dioxide molecule, energy is released as a photon. This process is called stimulating emission. The number of photons increases exponentially, If there are enough CO2 molecules. To achieve this, the emitted radiation between two mirrors is directed back and forth by the laser medium. A laser beam is created from the large number of photons, which enables precise cutting.
A co2 laser makes use of a tube filled with co2, n2, and he gas molecules. A strong electric field energizes the nitrogen gas molecules, which then transfer their energy to the co2 molecules. This causes the electrons in the co2 gas molecules to attain a higher energy level. Eventually, the energized electrons fall back into a stable state and emit photons. These photons then cause other nearby co2 molecules to also emit photons, creating a photon cascade. The photons then bounce between mirrors at either end of their containment tube, gaining energy on each pass. At a certain point, they have enough energy to pass through a semi-reflective mirror and are then directed to the focusing heat via a range of mirrors.
A fiber laser, on the other hand, is a solid-state laser. Instead of a gas-filled tube for generating the coherent light of the laser beam, it has a fiber optic filament with one section that is doped with neodymium atoms. Light is pumped into this filament. Once it reaches the doped section, the photons in the light waves excite the electrons in the neodymium atoms, which release other photons with a very specific wavelength. These photons then pass near other excited neodymium atoms which causes the excited electrons to drop down into a stable state, thereby emitting new photons causing a cascade effect. Fiber lasers make use of a device called bragg grating, which has the same function as the two mirrors in a co2 laser. The laser light reflects back and forth along the filament until it reaches the specific energy level required for it to pass through the grating as a coherent beam of light. This beam then travels down the length of the filament until it reaches a focusing mirror.
What is the CO2 Laser Used For?
CO2 Laser are used in the power range of 10 to 400 watts for cutting, perforating or engraving thin, organic materials such as wood, textiles or plastics. Very high cutting quality can be achieved by cutting PMMA (“acrylic”, “Plexiglas”) - when processed correctly, the cutting edges are just as transparent as all other surfaces of the workpiece.
CO2 Laser with increased power between 1 to 6 kilowatts are typical industrial lasers used for welding, hardening or remelting metals. In modern production, CO2 lasers are increasingly used for oxide-free laser cutting. In particular, the laser cutting machines are used for small batches in sheet metal processing. For larger quantities, however, punching is still the more economical option.
The CO2 Laser is used in a wide variety of industries. At the forefront is the automotive industry, where lasers are used to perforate the breaking point in the dashboard for airbags. Headliners or side panels are also manufactured using CO2 lasers.
Even in the clothing industry, there is a variety of applications for the CO2 laser. From fabric blanks to the texturing of jeans, the laser is an environmentally-friendly alternative to chemical and abrasive processes.
One future-proof market for the CO2 Laser is the cutting of fiber-reinforced plastics such as GRP and CRP. Here, it is the automotive, aviation or wind energy industries, where fiber-reinforced plastics are used as part of the answer to important issues of the times, such as sustainability, resource efficiency or climate protection.
Maintenance of CO2 Laser
Changing water and the water tank
It must be made sure that the laser tube is fully circulating water. The quality of the circulating water as well as the temperature of the water directly affects the service life of the laser tube. It is recommended that pure water must be used and the temperature of the water must be controlled below 35 degrees celsius. To clean the water tank, turn off the power and remove the water inlet pipe, and let the laser tube of water automatically into the tank. After that open the water tank and pump and clear all dirt that is present on the water pump. Replace the circulating water and restore the water pump back into the water tank. Turn on the power of the pump alone and run for 2 to 3 minutes to see if the laser tube is fully circulating water.
Cleaning the fan
After a long time of use, the fan can accumulate a lot of dust on the inside. This can make the fan make a lot of unusual sounds. When the fan makes these signs, remove the fan and clean the inside of the fan. The blades of the fan must be pulled out and wiped. This will ensure the efficient performance of the carbon dioxide laser.
Lens cleaning
The carbon dioxide laser has a lens that can easily catch dirt or other contaminants. These contaminants can cause damage to the lens. The lens must be removed and cleaned to ensure the efficient performance of the laser machine. When cleaning the lens, do not dip them in the cleaning fluid, but carefully wipe along the edges of the lens. Great care must be taken when wiping the lens since the
Components of CO2 Laser
There are three components of carbon dioxide lasers: A gain (or laser) medium, an energy source (also known as a pump), and an optical resonator. The function of the pump is to provide energy which is then amplified by the gain medium. A conversion of this energy into light will occur eventually and the optical resonator will reflect the light; the reflected light will then emit the final output beam.
Electrical current
The electrical current serves as the laser pump, which excites the gas medium.
Mixture of gasses
The mixture of gasses serves as the gain medium. The mixture of gasses is composed of carbon dioxide, nitrogen, hydrogen, and helium. The nitrogen, carbon dioxide, and helium constitute the vast majority of the mixture, even though the specific concentrations vary according to the intended use of the laser. The typical ratio is 1:1:8 for n2:Co2:He gas mixtures.
Specialized optical resonator
Co2 lasers operate entirely within the infrared spectrum and can attain high power outputs; their optical components are typically made of specialized (and often expensive) materials for example germanium, zinc selenide, silver, gold, and diamond.
What Are the Surgeries for Which a CO2 Laser Is Used?
Laser Resurfacing
CO2 lasers are in wide service for the treatment of skin disorders using tissue ablation and fractional beam techniques. Typical applications include scar removal and collagen regeneration promotion.
Incision and Excision
Lasers are often used to remove various types of growths such as warts, lesions, and nodules. CO2 lasers can also be employed as cutting tools in place of traditional scalpels. They produce precise cuts and also have a cauterizing effect caused by the heat of the beam that limits bleeding.
Dentistry
CO2 lasers provide significant benefits in dental procedures, as they are able to treat both hard and soft tissues. For example, a CO2 laser was first used to ablate tooth enamel in 2009 and has since then become prevalent.
Otolaryngology
“Otolaryngology” refers to the treatment of ear, nose, and throat conditions. The precision of the CO2 laser beam, coupled with its small size, makes a CO2 laser ideal for difficult-to-reach areas like the larynx. Airway lesions are easily treated with CO2 lasers.
Eye protection
The most important safety precaution to take when using a co2 laser is to wear eye protection. The laser beam emitted by the machine is very powerful and can cause serious eye damage if it is not properly shielded. It is important to wear safety glasses or a face shield when operating the machine. It is also important to make sure that the area around the machine is well-ventilated to reduce the risk of eye damage from the laser beam.
Protective clothing
It is also important to wear protective clothing when using a co2 laser. The laser beam can cause burns if it comes into contact with skin, so it is important to wear long sleeves and pants to protect your skin. It is also important to wear gloves to protect your hands from the heat generated by the laser beam.
Fire safety
When using a co2 laser, it is important to take fire safety precautions. The laser beam can cause materials to catch fire, so it is important to have a fire extinguisher nearby in case of an emergency. It is also important to make sure that the area around the machine is free of flammable materials.
Ventilation
It is also important to make sure that the area around the machine is well-ventilated. The laser beam can produce fumes and smoke, so it is important to make sure that the area is well-ventilated to reduce the risk of inhaling these fumes and smoke.
Maintenance
It is also important to make sure that the machine is properly maintained. It is important to check the machine regularly for any signs of wear and tear and to make sure that all of the safety features are functioning properly.
