Abstract

The paper presents experimental results of investigation of flash lamp pumped Nd:YAG laser operated at wavelength lambda =1.32 μm. Thresholds and resonator losses have been determined. In the active Q-switched mode, output pulses up to 29 mJ energy and pulse width of 37 ns have been obtained. Moreover, an intracavity Raman laser producing 1.53 μm radiation when pumped by Nd:YAG laser operated at 1.32 μm is presented. Output Raman pulses up to 10 mJ energy have been obtained. Raman beam cleanup and 36% energy conversion efficiency, have been observed.
