研究了采用面阵CCD探测器测量光束参量的技术问题,研制了一套高精度激光参量测量系统,对其光学系统像差与光场干涉原因进行了理论分析,实验测量了连续抽运1064nm固体模式发生器产生的基模厄米高斯光束,分析对比了其输出光束带有干涉条纹时对测量精度的影响,对光学系统的设计提出了具体技术要求,为同类装置的研制提供了参考依据。
The technical problems concerning the parameter measurement of the laser beam by using a CCD array is studied. A high-precision system for laser beam parameter measurement is developed. Its aberrations and optical interferences are analyzed in theory, and the laser beam with fundamental Gaussian mode by continuous a LD- pumped, solid-state mode generator with 1064 nm is measured. The influence of the beam output with different interference patterns on measurement precision is analyzed and compared with theoretical estimation. Then, the technical requests for designing the optical system are brought up, which provides reference for developing the similar instrument.
