Research output: Contribution to journalArticlepeer-review

Abstract

This paper considers the operating parameters of 24 cm3 active volume MnCl2-laser in a wide range of PRF (pulse repetition frequency). The maximum average power reaches 1 W at 17.6 kHz PRF and 0.2% efficiency. The laser generation on manganese metal at 125 kHz PRF has been obtained for the first time. The pumping conditions under which the output power of the visible spectral range starts exceeding the output power at IR lines have been determined. In particular, the electric field strength is calculated for the given GDT (gas discharge tube) parameters and buffer gas pressure. The dependence between the output power and pumping power is shown to be linear. The condition provides the change in IR and VIS output power relation is determined.
