Construction Of Co2 Laser

In co 2 molecular gas laser transition takes place between the vibrational states of carbon dioxide molecules.

Construction of co2 laser.

Its construction is simple and the output of this laser is continuous. In co 2 laser high power levels are obtained ranges from few watts to 15000 watts. The efficiency of co 2 gas lasers i e. In a molecular gas laser laser action is achieved by transitions between vibrational and rotational levels of molecules.

10 or higher is beat than he ne and argon lasers. Construction of carbon dioxide laser. It was invented by kumar patel of bell labs in 1964 and is still one of the most useful. Invented in 1964 co2 lasers have a long history of use and plenty of evidence to attest to their effectiveness and safety particularly on light skin tones.

There are several co2 lasers on the market and your provider will recommend the device percentage of skin targeted depth of treatment and. Doctors can customize co2 laser treatments to best suit your skin type and concerns. Co2 lasers have become the workhorse of the material processing industry because of their low cost below 100 per watt. It was the first molecular gas laser developed by indian born american scientist prof c k n pillai.

The ratio of output power to pump power can be as large as 20. They are also quite efficient. Carbon dioxide laser consists of a discharge tube having a diameter of 2 5cm and a length of about 5m. Co2 laser engraved walnut plaques were a popular item in the 1970s.

Co2 lasers are no longer considered in this role. The co 2 gas lasers are more versatile lasers. In those days co2 lasers were developed for defense but it was soon realized that enough of the wavelength is absorbed in the atmosphere to cause severe problems in pointing and focusing the beam at long distances. Its construction is simple and the output of this laser is continuous in the co2 molecular gas laser transition takes place between the vibrational states of carbon dioxide molecules.

The discharge tube is filled with a mixture of carbon dioxide nitrogen and helium gases in the ratio of 1 2 3 with water vapors. Carbon dioxide laser consists of a discharge tube having a diameter of 2 5cm and a length of about 5m. The carbon dioxide laser co 2 laser was one of the earliest gas lasers to be developed. Co2 molecular gas laser.
