The measurement of hel beam far field with hole grating beam sampler
A high power laser beam profile intensity measuring system using hole grating is introduced.The principle of hole grating sampler was analyzed.The HL CO2 laser focal irradiance distribution was measured with hole grating.The divergence and radius of laser beam were calculated.The beam quality can be valued by M2 factor.
