Abstract :
This paper investigates the possibility to improve the passively Q-switched emission of Nd lasers by direct pumping at 0.88 mum with diode lasers. Average output powers in excess of 1.0 W are reported by switching with Cr4+:YAG saturable absorber (SA) crystals. The influence of doping level on laser characteristics is discussed. Results obtained under the pump at 0.81 mum, into the highly-absorbing 4F5/2 level, are given for comparison.
