摘要
角漂移是微片激光器使用和优化设计的重要参数,但有关此类数据报道较少。基于四象限探测器和LabVIEW开发环境设计了一套测量激光器角漂移的测量系统。实现了对Nd…YAG微片激光器的角漂移的实时显示、读取和保存。测量了微片激光器激光指向角漂移的量级及变化规律,为微片激光器的使用和优化设计提供了理论依据。
Angular drift is one of the most important parameters of the optimization of microchip lasers＇ design and application, but such drift data haven＇t been reported. A measurement system of angular drift based on the four- quadrant photodetector and the LabVIEW software platform is developed to realize the real-time operation to angular drift signal, including display, reading and recoding. This system realized the measurement of angular driftrs order of magnitude and the variation regularity with pump power, provided the basic data for the optimization of microchip laserst design and application.
