Abstract

The technical problems concerning the determination of the laser beam parameters by using area array charge coupled device (CCD) detector were studied. The beam parameters of Hermite-Gaussian modes generated from laser diode (LD) pumped CW Nd:YAG laser with 1064 nm and a lamp pumped Q-switched Nd:YAG laser with 10 ns pulse width were experimentally measured. Comparing the measured beam quality factor M² with theoretical one, the measuring deviation of M² was less than 5%. The measuring error of the divergence was also less than 5%. The influences of various factors on the measured beam parameters were discussed.
