Construction And Working Of Co2 Laser

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

Construction and working of co2 laser.

The co2 laser produces a beam of infrared light with the principal wavelength bands centering on 9 6 and 10 6 micrometers. Carbon dioxide laser consists of a discharge tube having a diameter of 2 5cm and a length of about 5m. They are also quite efficient. N2 e n2 e.

In a molecular gas laser laser action is achieved by transitions between vibrational and rotational levels of molecules. Co2 laser cutters the c02 laser is one of the earliest gas lasers. Co2 laser principle construction and working. 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. It consists of a quartz tube 5 m long and 2 5 cm in the diameter. This discharge tube is filled with gaseous mixture of co2 active medium helium and nitrogen with suitable partial pressures. This process is represented by the equation.

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. Co2 laser principle construction and working. When an electric discharge occurs in the gas the electrons collide with nitrogen molecules and they are raised to excited states. With its high power and levels of control c02 lasers can be used for applications requiring precision mass production and most improtantly personalization.

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 lasers are the highest power continuous wave lasers that are currently available.
