@@@@Divergence angle of laser beams which used in laser measurement is an important signifcance. Divergence angle of laser beams is an important parameter of Medical laser. This article introduces three measurement ways of far-field divergence angle of laser beams. Far-feld divergence angle of the laser beams is calculated by CCD camera technique measuring spot size. These measurement ways are variously and simply used, they can help to check compliances of diverse clauses from different laser standards and make the tests convenient for test institution and company.
