报道了基于Nd:YAG晶体的4F3/2-4I13/2能级跃迁的1356 nm单波长LD端面抽运Nd:YAG激光器。采用LD端面抽运的平平腔结构，实现了2.4 W的连续波1356 nm和1414 nm双波长激光输出，光光转换效率为26.7%。通过在腔内插入1.3 μm波段的声光Q开关，增加了1414 nm波长的腔内损耗，从而获得了1356 nm的单波长连续和调Q脉冲激光输出。单波长输出功率为2 W；重复频率为5 kHz时，脉冲光平均功率为1.3 W，脉冲宽度为71 ns，峰值功率为3.66 kW。

LD pumped Nd:YAG crystal laser emitting at 1356 nm single wavelength from 4F3/2-4I13/2 translation is reported. Continuous-wave (CW) output power of 2.4 W with 1356 nm and 1414 nm dual-wavelength is achieved using flat-flat cavity, and the corresponding optical conversion efficiency is 26.7%. With the insertion of an acousto-optic Q-switcher in the cavity, the loss for 1414 nm increases, so that the 1356 nm CW single wavelength as well as the Q-swithched pulse are achieved. At the pulse repetition frequency of 5 kHz, the pulse width is 71 ns and the peak power is about 3.66 kW.
