对1085和1093 nm附近的双波长a切Nd：MgO：LiNbO 3激光器进行了实验和理论研究。同时双波长发射主要归因于在流形4 I11/2中斯塔克分裂能级的玻尔兹曼分布。在吸收泵浦功率为7.45 W时，获得了1.23 W的最大连续波输出，斜率效率为21.2%。采用Cr：YAG作为可饱和吸收体，在重复频率为24 kHz时，获得了脉宽为28 ns的最短脉冲，峰值功率为729 W。
Diode-pumped dual-wavelength a-cut Nd:MgO:LiNbO3lasers near 1085 and 1093 nm were experimentally and theoretically investigated. The simultaneous dual-wavelength emitting was mainly attributed to the Boltzmann distribution of the occupation in the Stark-split energy-levels in manifold4I11/2. Under an absorbed pump power of 7.45 W, a maximum continuous wave (CW) output power of 1.23 W was obtained, giving a slope efficiency of 21.2%. Using Cr:YAG as saturable absorber, the shortest pulse duration of 28 ns was obtained with a repetition rate of 24 kHz, resulting in a peak power of 729 W.
