Abstract
A copper vapor laser with active medium length of 60 cm and bore of 16 mm has been operated and optimized using different buffer gases to investigate the effect of the gas flow rates on the output power. It is found that there is a special optimum gas flow rate associated with the type of buffer gas.
Highlights
The lasers are sources of light with very special properties that emit light based on the stimulated emission of electromagnetic radiation
Three gases, Ne, He, and air have been used as buffer gas individually, and the output powers are measured under same conditions, that is, the electrical input power is kept at 1.7 kW and the pulse repetition frequency is fixed at 20 kHz
The laser output powers with these gases are measured versus gas flow rates, individually
Summary
The lasers are sources of light with very special properties that emit light based on the stimulated emission of electromagnetic radiation. (2016) Experimental Study of Buffer Gas Flow Rate Effect on Output Power of a Copper Vapor Laser. The buffer gas is employed in CVL tube to increase the output power and improve the laser performance [34] [35]. It provides a discharge medium before reaching the discharge tube to the temperature required for copper vapor production. Some similar works have been studied generally, which investigated the effects of buffer gas pressure and some additive gases on CVL output characteristics. The behavior of the laser output power versus gas flow rate of these gases has been investigated to obtain the optimum conditions.
