A CW output as high as 66 W at 1319 nm was achieved under the pump power of 460 W, corresponding to a coversion efficiency of 14.3%. A maximum average power of 8.9 W of TEM00 mode was obtained in Q-switched operation at the repetition rate of 8 kHz. The performance of the laser considering the thermal lens effect induced by pump power was also analyzed.展开更多

文摘We demonstrated the highly efficient continuous wave （CW） and Q-switched infrared laser from a diode- side-pumped Nd：YAG crystal.
