Abstract

The stable ∼ 3 μm self-pulsing laser has been achieved for the first time, along with compact and efficient pulse compression and amplification, based on the growth of novel Ho,Pr:GdScO₃ crystals. Using the conventional Czochralski method, we have grown novel Ho,Pr:GdScO₃ crystals with three different polarization-directions and discovered the self-pulsing effect within the crystals. Leveraging this phenomenon, we have successfully obtained linearly-polarized self-pulsing lasers in the mid-infrared (MIR) band and demonstrated the strong stability of the pulse trains both theoretically and experimentally. In addition, a novel pulse compression and enhancement method has been developed to maximize the performance of the self-pulsed Ho,Pr:GdScO₃ lasers. Compared to self-pulsed lasers, the novel low-loss pulse compression can provide a more compact and efficient solution for enhancing the peak power of laser pulses. The results combine self-pulsed Ho,Pr:GdScO₃ crystals with pulse compression and enhancement techniques to facilitate miniaturization and integration of high-peak-power, narrow-pulse-width MIR pulsed lasers.

Ho3+/Pr3+ 共掺杂激光器中的中红外自脉冲生成和增强型脉冲压缩

基于新型 Ho,Pr:GdScO3晶体的生长，我们首次实现了稳定的 ∼ 3 μm 自脉冲激光，以及紧凑高效的脉冲压缩和放大。利用传统的 Czochralski 方法，我们生长出了具有三种不同偏振方向的新型 Ho,Pr:GdScO3 晶体，并发现了晶体内部的自脉冲效应。利用这一现象，我们成功获得了中红外（MIR）波段的线性偏振自脉冲激光器，并在理论和实验上证明了脉冲序列的强大稳定性。此外，我们还开发了一种新颖的脉冲压缩和增强方法，以最大限度地提高自脉冲 Ho,Pr:GdScO3 激光器的性能。与自脉冲激光器相比，新型低损耗脉冲压缩能为增强激光脉冲的峰值功率提供更紧凑、更高效的解决方案。该成果将自脉冲 Ho,Pr:GdScO3 晶体与脉冲压缩和增强技术相结合，促进了高峰值功率、窄脉冲宽度近红外脉冲激光器的小型化和集成化。
