Paper Abstract

With the development of laser technology, higher requirement is presented on measurement technology of laser beam. The measurement technology of laser beam develops from the original Knife-edge method, Slit scanning method into the latter Shack-Hartmann method. The test index of laser beam also develops from originally testing power, wavelength into putting much value on the testing of wavefront, and characteristic value of a laser beam. In this paper, we go deep into study the method of measurement of laser beam and present a laser beam measurement method which is takes photos on focal plane to calculate the wavefront and the laser characterization. The difference between Shack-Hartmann method and this method is analyzed. The results of experiment show that, this method is simple apparatus, and high precision, and it will be a development tendency on the laser beam measurement field, in the future.
