Jun 20, 2020 · In carbon dioxide laser, Co2 gas molecules are used as the active medium and population inversion is achieved by the electrical pumping method. Principle. The active medium is a gas mixture of CO2, N2 and He. The laser transition takes place between the vibrational states of CO2 molecules. Energy states of CO2 molecules.
The device of a CO2 laser produces light when electricity runs through a gas-filled tube. Furthermore, mirrors are at the end of the tube. One of the mirrors is fully reflective and the other allows some light through it. The gas mixture is usually composed of carbon dioxide, hydrogen, nitrogen, and helium.
Oct 26, 2023 · A carbon dioxide (CO 2) laser is a type of gas laser widely used in various applications due to its high efficiency and output power. Originally developed in the mid-1960s, it has become one of the most beneficial industrial tools in the 21st century. Principle and Construction. A CO 2 laser operates by exciting carbon dioxide gas with ...
Sep 11, 2023 · The CO2 laser is a high-efficiency laser that minimizes damage to the working medium. It emits an invisible laser with a wavelength of 10.6μm, making it an ideal laser. According to the working condition of the gas, it can be divided into closed and circulation types.
In this video, we will learn about the CO2 laser's construction, working principle and actual working. This is one of the fascinating concepts. Watch and lea...
A test target bursts into flame upon irradiation by a continuous-wave kilowatt-level carbon-dioxide laser. The carbon-dioxide laser (CO 2 laser) was 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.
Dec 16, 2021 · For any laser to work, the first step is to give extra energy to the lasing medium. This is called excitation. As it turns out, if you excite nitrogen, it can then transfer its energy surplus to neighboring CO 2 molecules.
The CO 2 laser ( carbon dioxide laser) is a molecular gas laser with emission in the long-wavelength infrared spectral region. It is based on a gas mixture as the gain medium, which contains carbon dioxide (CO 2 ), helium (He), nitrogen (N 2 ), and possibly some hydrogen (H 2 ), oxygen (O 2 ), water vapor and/or xenon (Xe).
Mar 14, 2018 · A CO2 laser is a type of gas laser. In this device, electricity is run through a gas-filled tube, producing light. The ends of the tube are mirrors; one of which is fully reflective and the other which lets some light through.
A diffusion-cooled high-power CO 2 laser, the so-called slab laser, promises to replace flowing gas lasers in many applications because of a range of advantages offered by the basic design. The same design is used for low-power slab lasers, with the only difference being a sealed gas charge tube.
