Laser technology has made our lives much easier than before. One example is CO2 laser technology. CO2 lasers blend gases to make a precise invisible beam. They’re known for accuracy and work well with various materials and in different industries.
In this blog post, you’ll learn all the simple details, from how they work to the things they can do. Find out why CO2 lasers are handy for different jobs and how they compare to other laser technology. Let’s get started!
What is CO2 Laser Technology?
The CO2 laser is an innovative technology that creates a precise invisible beam by employing a mixture of gases. According to DermNet, the gas mixture comprises carbon dioxide, nitrogen, and helium. The electric discharge results in laser beam emission.
CO2 laser technology is renowned for its accuracy. It’s widely used in cutting, joining materials, and laser treatments in medicine and research. It is also acknowledged for its versatility. It efficiently works across diverse materials and industries.
How Do CO2 Lasers Work?
The operational sequence of a CO2 laser involves distinct stages, commencing with the inception of the laser beam within the resonator.
A resonator is a cylindrical glass tube housing carbon dioxide, nitrogen, and helium. This resonator features a reflective mirror at one end and a semi-reflective mirror at the opposite end. Ionization of the gas in the resonator is achieved through an electric field, energizing the nitrogen molecules and subsequently transferring this energy to the CO2 molecules, prompting electron movement to higher energy levels.
According to the Defence Technical Information Center, as these excited CO2 molecules undergo a transition to lower energy levels, they emit photons. The emitted photons induce a chain reaction, compelling nearby excited CO2 molecules to release photons in the same direction.
This cascade of photons is perpetuated as they bounce between the mirrors, prompting the emission of additional photons from adjacent CO2 molecules. This process persists until a critical mass of reflected photons generates a coherent beam of light that penetrates the semi-reflective mirror. The resultant light is then channeled through a lens, concentrating it into a high-energy intensity point for utilization in industrial or medical applications.
6 Types of CO2 Laser
There are 6 main types of CO2 laser, have a look at them:
1. Longitudinal-Flow Laser
These lasers contain a long, thin tube that carries the laser beam along its length. They are commonly used for actions such as cutting, engraving, and marking due to their ability to transmit focused energy across great distances properly. Longitudinal mode provide predictable results by continually eliminating laser gas from the tube using a vacuum pump.
2. Transverse-flow Laser
In contrast to longitudinal-flow lasers, the laser beam in transverse-flow systems travels across the width of the tube. This configuration is effective and appropriate for high-power workloads. Using this technology, the laser may handle greater gas flow, improving cooling and making the laser more robust in harsh environments.
3. Sealed-off CO2 Lasers
Seal CO2 lasers limit the laser gas mixture inside a sealed tube, making them compact and efficient. To prevent CO2 molecules from breaking down, modest quantities of hydrogen, water vapor, and oxygen are added to the gas mixture rather than replacing it entirely. Nickel cathodes heated to 300°C catalyze this process. Mirrors at either end provide a resonant cavity, increasing the laser’s operational life by several thousand hours.
4. Waveguide Lasers
Waveguide lasers employ a waveguide structure to guide the laser beam, resulting in high beam quality. They effectively absorb heat loss in their smaller lasing volume and larger resonator surface area. This makes them ideal for scientific research and medical operations where precise beam control is required.
5. Tea (Transversely Excited Atmospheric) Laser
TEA lasers are ideal for pulsed laser applications such as material removal and spectroscopy due to their high pulse rate. Short pulses of discharge voltage across the gas flow lessen the probability of arcing.
Electrodes connected in series along the discharge tube provide steady functioning even at high pressures. While they normally have average output powers of below 100 W, TEA lasers can generate tens of kilowatts of power with high pulse repetition rates.
