The carbon dioxide laser co 2 laser was one of the earliest gas lasers to be developed.
Construction of co2 laser.
Doctors can customize co2 laser treatments to best suit your skin type and concerns.
Construction of carbon dioxide laser.
Co2 laser engraved walnut plaques were a popular item in the 1970s.
Carbon dioxide laser consists of a discharge tube having a diameter of 2 5cm and a length of about 5m.
It was the first molecular gas laser developed by indian born american scientist prof c k n pillai.
It was invented by kumar patel of bell labs in 1964 and is still one of the most useful.
In co 2 laser high power levels are obtained ranges from few watts to 15000 watts.
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.
Co2 lasers are no longer considered in this role.
In a molecular gas laser laser action is achieved by transitions between vibrational and rotational levels of molecules.
Its construction is simple and the output of this laser is continuous.
The efficiency of co 2 gas lasers i e.
10 or higher is beat than he ne and argon lasers.
Co2 lasers have become the workhorse of the material processing industry because of their low cost below 100 per watt.
The ratio of output power to pump power can be as large as 20.
Carbon dioxide lasers are the highest power continuous wave lasers that are currently available.
In co 2 molecular gas laser transition takes place between the vibrational states of carbon dioxide molecules.
Today i will discuss the construction of carbon dioxide laser.
They are also quite efficient.
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.
The co 2 gas lasers are more versatile lasers.
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.
Co2 molecular gas laser.
Carbon dioxide laser consists of a discharge tube having a diameter of 2 5cm and a length of about 5m.
