连续波激光和脉冲激光对光学材料不同的破坏机理决定了解决其光学稳定性的不同途径。为了确定红外光学材料破坏机理变更的边界，作者将所有激光作用都看为脉冲的，确定了激光破坏阈值，并记录其特点。为了研究KCl单晶的破坏特点，建立了图1所示装置。它可用宽孔径激光照射样品 The different failure mechanisms of CW and pulsed lasers on optical materials determine different ways of resolving their optical stability. In order to determine the boundary of the change mechanism of the failure of infrared optical materials, the authors considered all laser effects as pulses, determined the laser damage threshold, and recorded its characteristics. In order to study the destruction of KCl single crystal characteristics, the establishment of the device shown in Figure 1. It can be irradiated with a wide aperture laser sample
