Study on damage effect and threshold of high energy 1.06µm-wavelength long-pulse laser to photo detector

摘要

In this paper, the damage mechanism of high energy laser to photoelectric detector is studied. With a long pulse laser at the wavelength of 1.06µm, energy saturation threshold measurement and damage test for CCD camera and four-quadrant detector are performed separately. The test results will play important roles not only in design and development of laser but also in evaluation of operational effectiveness.
