Paper Abstract

The Q-switched laser with triangle slab made of Nd:YAG crystal side pumped by 600-W quasi-cw diode laser stack has been designed. The multimode (M2≈2.6) output energy of about 42 mJ was demonstrated in free running mode for 110-mJ pump energy. In Q-switch experiments, the KDDP Pockels cell was placed between the slab and rear mirror in plane-plane cavity with output coupler of 84% transmission. The energy of 8 mJ in 2.1-ns pulse duration was obtained for near TEM00 output beam. For passive Q-switching by means of Cr:YAG crystal of 12.6% unsaturated transmission the energy of 5.1 mJ in 2.5-ns pulse duration was obtained for output beam close to TEM00 mode.
