Waveless front detector far-field laser beam shaping device and method based on double-wavefront corrector
A wavefront corrector and wavefront detector technology, applied in optics, instruments, optical components, etc., can solve the problem of limited shaping range and accuracy of a single deformable mirror laser beam shaping system, increasing system complexity and cost, and laser beam shaping. The process is complicated and other problems, so as to achieve the effect of far-field light intensity shaping, shortening the optimal control time, and improving the shaping range and accuracy
