Temporal and Spatial Distribution of Output Power from Different Electron Temperature in Copper Vapour Laser

Abstract

We have investigated the radial profiles at different times during the formation of the laser pulse. It is found that the radial profile of the spectral emission is not same at all the times during the formation of the laser pulse. The radial profile go on changing the shape as a function of time. During the formation of a laser pulse the electron temperature dose not remain same consequently the radial profile of spectral emission also change. In some cases, when the electron temperature is relatively low, the radial profiles are almost Gaussian at all the times, however the peak height goes on changing. In some other cases in a part of the beam the radial profiles are like Gaussian and in remaining part they exhibit dip non-Gaussian distribution. If the exciting pulse parameters are change the profiles remains non-Gaussian through out the formation of a beam. If the temperature is made very high beam may become annular in shape.
