摘要
液晶相位调控器件在聚变点火、激光加工、光电对抗、激光雷达、激光通讯、激光防护等高功率激光领域有着非常广泛的应用及应用前景。但受限于构成器件材料自身抗激光损伤能力的限制以及缺乏对高功率激光辐照下液晶相位调控器件相位调控性能退化及损伤特性的系统研究,目前液晶相位调控器件的激光耐受力还难以满足高功率激光系统的应用和发展需求。为指导高激光耐受力液晶相位调控器件的制备工艺优化,对液晶相位调控器件在高峰值和高平均功率激光应用下出现的损伤现象以及性能退化进行了综述,最后对液晶相位调控器件激光耐受力提升方法做了总结和归纳。
The liquid crystal phase modulators(LCPMs) have applications and prospects in fusion ignition,laser processing, optoelectronic countermeasure, laser radar, laser communication, laser protection and so on.However, owing to the limited laser damage resistance of the materials constituting the LCPMs as well as insufficient system research on the laser damage and the phase modulation performance degradation of LCPMs induced by high power lasers, the laser handling power of LCPMs cannot satisfy the requirements of high power laser developments.To provide guidance for optimizing the fabrication process of LCPMs with high laser handling power, we reviewed the laser damage and the phase modulation performance degradation characteristics of LCPMs irradiated by highpeak-power lasers and high-average-power-lasers and then summarized the methods to improve the laser handling power of LCPMs.
