Abstract In this paper, the characteristic of passively Q-switched Nd:GdNbO4 laser using two-dimension (2D) material MoS2 as SA under 879 nm direct pumping was demonstrated for the first time. When absorbed pump power was 4.36 W, the maximum average output power, narrowest pulse width and highest repetition frequency were measured as 427 mW, 740 ns and 89 kHz, respectively. At the same absorbed pump power, the maximum pulse energy and peak power were calculated as 4.8 μJ and 6.48 W, respectively.

摘要 本文首次展示了在879 nm直接泵浦下使用二维(2D)材料MoS2作为SA的被动调Q Nd:GdNbO4激光器的特性。当吸收泵浦功率为 4.36 W 时，测得的最大平均输出功率、最窄脉冲宽度和最高重复频率分别为 427 mW、740 ns 和 89 kHz。在相同的吸收泵浦功率下，计算出的最大脉冲能量和峰值功率分别为 4.8 μJ 和 6.48 W。
