Construction And Working Of Co2 Laser

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.

Construction and working of co2 laser.

This process is represented by the equation. The laser transition takes place between the vibrational states of co2molecules. Co2 laser working and construction duration. It was invented by kumar patel of bell labs in 1964 and is still one of the most useful.

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. N2 e n2 e. This video lecture will explain the working of carbon dioxide laser.

It consists of a quartz tube 5 m long and 2 5 cm in the diameter. When an electric discharge occurs in the gas the electrons collide with nitrogen molecules and they are raised to excited states. Carbon dioxide laser consists of a discharge tube having a diameter of 2 5cm and a length of about 5m. 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.

In a molecular gas laser laser action is achieved by transitions between vibrational and rotational levels of molecules. With its high power and levels of control c02 lasers can be used for applications requiring precision mass production and most improtantly personalization. Construction of carbon dioxide laser. Co2 laser principle construction and working.

They are also quite efficient. This discharge tube is filled with gaseous mixture of co2 active medium helium and nitrogen with suitable partial pressures.

Hello guys today i am going to explain you about the construction working and principle of co2 laser in the most easiest manner so that it will long last in your mind and at the same time help.

Co2 laser principle construction and working. The co2 laser produces a beam of infrared light with the principal wavelength bands centering on 9 6 and 10 6 micrometers.
