摘要
为解决目前各激光器检测仪功能单一、检测精度低等问题,研制了一种新型智能激光器参数检测系统。该系统采用现代控制技术和微机软件,且配有特定结构的分光束光学系统,能同时实现辐射器光轴平行性、光束性能参数(包括光束发散能量、脉宽、编码精度)、光轴稳定性测试和系统整体性能测试。通过引入红外自准直仪使系统的角分辨率达到了2″,借助示波器捕获窄达100ps的激光脉冲,高精度、大动态范围的激光能量计可精确测量出激光的能量。
To solve the problems existing in the present test system such as low testing precision and simple function, a new intelligent test system is developed, which involves control technology, quick and convenient WIN32 computer software and a special beam splitter system. It can simultaneously measure optical axis parallelism, width and energy of the pulse, beam divergence, beam axis stability, and system performance. A high-powered infrared autocollimator is adopted to ensure 2＂ of spatial resolution, a 15GHz oscilloscope is used to capture the laser pulse as narrow as 100 ps, and an accurate laser power meter with large dynamic range is used to obtain accurate energy measurement of the laser pulse. The system is checked and accepted, and all the performance parameters meet the design requirements.
