Construction And Working Of Co2 Laser

Co2 laser principle construction and working.

Construction and working of co2 laser.

The ratio of output power to pump power can be as large as 20. Co2 laser working and construction duration. This discharge tube is filled with gaseous mixture of co2 active medium helium and nitrogen with suitable partial pressures. Co2 laser cutters the c02 laser is one of the earliest gas lasers.

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. With its high power and levels of control c02 lasers can be used for applications requiring precision mass production and most improtantly personalization. When an electric discharge occurs in the gas the electrons collide with nitrogen molecules and they are raised to excited states. 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.

This process is represented by the equation. Carbon dioxide laser consists of a discharge tube having a diameter of 2 5cm and a length of about 5m. The co2 laser produces a beam of infrared light with the principal wavelength bands centering on 9 6 and 10 6 micrometers. Developed by kumar patel in 1964 it is still one of the most useful lasers today.

The carbon dioxide laser was one of the earliest gas lasers to be developed. The laser transition takes place between the vibrational states of co2molecules. This video lecture will explain the working of carbon dioxide laser. Carbon dioxide lasers are the highest power continuous wave lasers that are currently available.

N2 e n2 e. 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. It was invented by kumar patel of bell labs in 1964 and is still one of the most useful. Dr sushil kumar master apni physics 89 808 views.

In a molecular gas laser laser action is achieved by transitions between vibrational and rotational levels of molecules. Co2 laser principle construction and working.
