The paper presents experimental results of flashlamp pumped Nd:YAG laser operated at wavelength (lambda) equals 1.1318 micrometers , (lambda) equals 1.338 micrometers , (lambda) equals 1.356 micrometers , (lambda) equals 1.414 micrometers and (lambda) equals 1.444 micrometers . Thresholds and resonator losses at these lines have been determined. The laser was also operated at line 1.318 micrometers in the Q-switched mode both active and passive. In active Q- switching, output pulses up to 29 mJ energy and pulsewidth of 41 ns have been obtained. In passive Q-switching with V2+: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 micrometers radiation when pumped by Nd:YAG laser operated at 1.318 micrometers is presented. Output Raman pulses up to 10 mJ energy have been obtained. Raman beam cleanup and 36 percent energy conversion efficiency have been observed.
