Construction of ruby laser. Carbon dioxide lasers are the highest power continuous wave lasers that are currently available.

Laser medium the pump source and the optical resonator. Co2 laser engraved walnut plaques were a. Co2 laser principle construction and working. Construction of carbon dioxide laser.

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. It was the first molecular gas laser developed by indian born american scientist prof c k n pillai. 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 molecular gas laser.

The ratio of output power to pump power can be as large as 20. They are also quite efficient. The power output from this laser is 10kw. 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 in the co2 molecular gas laser transition takes place between the. Co2 lasers have become the workhorse of the material processing industry because of their low cost below 100 per watt. A ruby laser consists of three important elements. This video lecture will explain the working of carbon dioxide laser.

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. The efficiency of co 2 gas lasers i e. Working of helium neon laser. The carbon dioxide laser co 2 laser was one of the earliest gas lasers to be developed.

In co 2 molecular gas laser transition takes place between the vibrational states of carbon dioxide molecules. 10 or higher is beat than he ne and argon lasers. In co 2 laser high power levels are obtained ranges from few watts to 15000 watts. The helium neon lasers are most commonly used in college laboratories whereas the carbon dioxide lasers are used in industrial applications.

Reflect most part of the light but allows some part of the light to produce the laser beam. The co 2 gas lasers are more versatile lasers. It emits deep red light of wavelength 694 3 nm. Dr sushil kumar master apni physics 89 808 views.
