The paper presents experimental results of investigation of flashlamp pumped Nd:YAG laser operated at, wavelengths lambda = 1.318 [my]m, lambda = 1.338 [my]m, lambda = 1.356 [my]m, lambda = 1.414 [my]m and lambda = 1.444 [my]m. Thresholds and resonator losses at these lines have been determined. The laser was also operated at line 1.318 [my]m in the Q-switched mode, both active and passive. In active Q-switching, output pulses up to 29 mJ energy and pulsewidth of 4l ns have been obtained. In passive Q-switching with V'3+:YAG crystalline saturable absorber, on the other hand, output pulses up to 4.5 mJ energy and 35 ns duration have been generated. Moreover, an intracavity Raman laser producing 1.53 [my]m radiation when pumped by Nd:YAG laser operated at 1.318 [mi]m is presented. Output Raman pulses up to 10 mJ energy have been obtained. Raman beam cleanup and 36% energy conversion efficiency have been observed.
