| Abstract: | The lasing properties of Nd:KGW crystal in free-running mode with different transmission of the output couplers are reported. The best results have been obtained with the output coupler of 24% transmission. The slope efficiency is 1.0% and the extrapolated energy threshold is 0.54 J. A comparative experiment of Nd:KGW and Nd:YAG laser crystals has been cavried out under identical experimental conditions in both free-running and Q-switched modes. The much higher efficiency and the lower threshold for Nd:KGW (Nd: 2.2 at. -%) compared to Nd:YAG (Nd: 1.1 at. -%) at 1.064 μm are demonstrated in both operation mode. |
