我们对 K2H(2−x)DxPO4 晶体中激光诱导的体损伤的形态进行了详细研究。我们看到内部损坏部位的三个不同区域：一个充满碎石的核心，一个可能已熔化和压实的外壳，以及一个稍加修改的冲击材料的较大外部区域。这些区域的性质对于理解激光引起的损伤对光散射的影响非常重要，这对于高功率激光操作具有重要意义。我们提出了一个简单的模型来解释我们观察到的形态和光散射。我们对 K2H(2−x)DxPO4 晶体中激光诱导的体损伤的形态进行了详细研究。我们看到内部损坏部位的三个不同区域：一个充满碎石的核心，一个可能已熔化和压实的外壳，以及一个稍加修改的冲击材料的较大外部区域。这些区域的性质对于理解激光引起的损伤对光散射的影响非常重要，这对于高功率激光操作具有重要意义。我们提出了一个简单的模型来解释我们观察到的形态和光散射。
We present a detailed study of the morphology of laser-induced bulk damage in K2H(2−x)DxPO4 crystals. We see three distinct regions of the internal damage sites: a rubble filled core, a shell that has probably been melted and compacted, and a larger outer region of slightly modified shocked material. The nature of these regions is important for understanding the impact of laser-induced damage on light scattering, which can be significant for high-power laser operation. We propose a simple model to explain the morphology and light scattering we observe.We present a detailed study of the morphology of laser-induced bulk damage in K2H(2−x)DxPO4 crystals.
