Spatial Filter Pinhole Alignmenton High Power Laser Facility
Using grating diffraction of a new far field alignment package, the spatial filtering pinholes alignment in two spatial filters especially on the same optical path is achieved. This scheme overcomes the shortcomings of pinholes size requirement of traditional method, realizes two pinholes center aligned while maintaining beams far|field alignment function. The new method has been successfully applied to the Israel project. The facility experiment results show that the alignment accuracy is less than 3% of the pinhole diameter which is 15 times of the beams diffraction limit, which meets the requirements of facility debugging (<4% of the pinhole diameter).
