Laser wave-front measurement of ICF amplifiers using hartmann-shack wave-front sensor

摘要

Known the wave-fronts of the ICF amplifiers is very important for impriving the design and adjustment of the amplifiers and desiging the adaptive optical system that can be used to shape the beam or clean it up. Because the pulse of ICF laser is ns scale, the wave-front can not be measured with common methods. In this paper, a method with a Hartmann-Shack wave-front sensor based on the protressive scan CCD camera is introduced. The test results show that this method is effective.
