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