Abstract
As much as 1.6-W average output power was emitted in a simple setup fr om a diffusion-bonded Nd:YAG rod with 70-100-ns Q-switched pulses at 9 46 nm and repetition frequencies between 15 and 45 kHz at 22-W inciden t diode-pump power. A Cr4+:YAG crystal with a bleachable loss of appro ximately 2.5% and a length of 0.5 mm was used as a saturable absorber. The extraction efficiency was 47% in comparison with the continuous-w ave laser output power of 3.37 W in the free-running regime. (C) 1998 Optical Society of America.
