Paper Abstract

In many applications of ion gas lasers the laser beam is used for specified short periods of time. For these applications laser systems are typically equipped with mechanical shutter. In consequence of this regime of laser beam modulation the peak output power of laser pulses are equal to constant output power generated by laser. Results of our experiments described in 1 shows that in pulse mode of supplying discharge current it is possible to obtain significant increase of peak value of laser output power in comparison with laser output power generated in CW operation (without current modulation). In this paper we present results of our following experiments on pulse supply of ion laser filled with argon-krypton mixture. For this laser operates in pulse regime we have observed the significant - up to 3.5 times - increase of peak laser output power. This effect was especially strong in the UV range. This paper anwe measured in far field the sigxture percentage on the output power of individual Ar and Kr spectral lines in pulse operation. The research suggests that the most significant effect results from different gas pumping rate of the mixture components in the discharge path.a
