Abstract

The optical parametric amplification process in the mid-infrared (MIR) 3–5 μm region of nonlinear crystal LiInS ₂ (LIS) has been investigated. The LIS crystal was pumped by a 1064 nm laser with a pulse width of 30 picoseconds and seeded by a tunable laser generated from a KTP-OPG/OPA pumped by the second harmonic (SH) of the same 1064 nm laser. In the experiment, the 3.28–5.50 μm tunable idler was realized. When the fixed pump energy is 8.75 mJ, the idler energy obtained is 72.2 μJ at 3.28 μm and 63.3 μJ at 5.50 μm. The maximum idler energy of 179.4 μJ at 4.70 μm is reached at a pump energy of 12.5 mJ, and the optimal photon conversion efficiency is 6.36% at the pump energy of 11.5 mJ. Finally, the optical parametric frequency conversion parameters and performance in the 3–5 μm of several typical new crystals (BGSe, LISe, AGS, HGS, and LGS) developed in recent years are briefly compared and summarized.

关于 LiInS2 中 3-5 μm 中红外光参量放大特性的研究

研究了非线性晶体 LiInS2（LIS）在中红外（MIR）3-5 μm 区域的光参量放大过程。LIS 晶体由脉冲宽度为 30 皮秒的 1064 纳米激光器泵浦，并由 KTP-OPG/OPA 产生的可调谐激光器播种，KTP-OPG/OPA 由同一 1064 纳米激光器的二次谐波 (SH) 泵浦。在实验中，实现了 3.28-5.50 μm 的可调谐惰轮。当固定泵浦能量为 8.75 mJ 时，在 3.28 μm 处获得的惰极能量为 72.2 μJ，在 5.50 μm 处为 63.3 μJ。当泵浦能量为 12.5 mJ 时，4.70 μm 处的最大惰极能量为 179.4 μJ，而当泵浦能量为 11.5 mJ 时，最佳光子转换效率为 6.36%。最后，简要比较和总结了近年来开发的几种典型新型晶体（BGSe、LISe、AGS、HGS 和 LGS）在 3-5 μm 波长范围内的光参量频率转换参数和性能。
