This video lecture will explain the working of carbon dioxide laser.
Construction working of co2 laser.
It was the first molecular gas laser developed by indian born american scientist prof c k n pillai.
In co 2 molecular gas laser transition takes place between the vibrational states of carbon dioxide molecules.
They are also quite efficient.
The carbon dioxide laser usually produces a beam that is invisible to the naked eye but can go through the atmosphere so that it can be used as a cutting or welding device in industry.
Co2 molecular gas laser.
It emits deep red light of wavelength 694 3 nm.
It was invented by kumar patel of bell labs in 1964 and is still one of the most useful.
Working of helium neon laser.
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.
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.
Reflect most part of the light but allows some part of the light to produce the laser beam.
The ratio of output power to pump power can be as large as 20.
The helium neon lasers are most commonly used in college laboratories whereas the carbon dioxide lasers are used in industrial applications.
Co2 laser principle construction and working.
The efficiency of co 2 gas lasers i e.
Its construction is simple and the output of this laser is continuous.
Its construction is simple and the output of this laser is continuous in the co2 molecular gas laser transition takes place between the.
The power output from this laser is 10kw.
10 or higher is beat than he ne and argon lasers.
Carbon dioxide lasers are the highest power continuous wave lasers that are currently available.
Construction of ruby laser.
Co2 lasers have become the workhorse of the material processing industry because of their low cost below 100 per watt.
Construction of carbon dioxide laser.
Co2 laser engraved walnut plaques were a.
Ruby laser is one of the few solid state lasers that produce visible light.
Laser medium the pump source and the optical resonator.
In a molecular gas laser laser action is achieved by transitions between vibrational and rotational levels of molecules.
In co 2 laser high power levels are obtained ranges from few watts to 15000 watts.
A ruby laser consists of three important elements.
