The switching time, that is, the entire unit time resolution, depending on the pump CS2 Kerr medium width of laser pulse. The optical Kerr effect refers to the media after laser irradiation to produce strong electric fields, so as to change the refractive index of a photoelectric effect. The refractive index change leads to the self-focusing nonlinear optical effect, the phase modulation and modulation instability, and is the foundation of Kerr lens mode locking. Purpose and significance of this topic is designed to understand the basic principles of optical Kerr shutter and optical Kerr effect, application, and master the optical Kerr shutter the influence factors of the strobe light efficiency measurement method. This design plans to change the laser power, signal light transmittance measurement analysis, to study the performance of optical Kerr shutter, as to provide theoretical basis for optimizing the optical Kerr shutter performance and experimental support.Key words:Laser power、Optical Kerr shutter、Optical Kerr effect、Performance impact第1章绪论1.1选题的目的与意义光克尔快门是由一个强的偏振光来控制其开关，因此快门的性能受到激光功率的影响。其开关时间，也就是整个装置的时间分辨率，取决于泵浦光克尔介质CS2激光脉冲的宽度。而光克尔效应是指介质经激光照射后产生很强的电场，从而改变其折射率的一种光电效应。这种折射率的变化导致了非线性光学效应的自聚焦，自相位调制以及调制的不稳定性，并且是克尔透镜锁模的基础。此选题的目的和意义旨在了解光克尔快门和光克尔效应的基本原理以及应用，并掌握光克尔快门对光的选通效率的影响因素的测量方法。本设计拟改变激光功率，测量分析信号光的透过率，对光克尔快门性能进行研究，为优化光克尔快门性能提供理论依据和实验支撑。1.2激光功率对光克尔快门性能的影响的发展趋势由于光克尔效应在各种介质中都能够发生, 并且不受光谱的限制, 而且光克尔快门结构简
