Paper Abstract

As a leading manufacturer of pulsed lasers that vary from one millijoule femtosecond systems to 120 joule glass lasers, beam quality is very important to us as a measure of performance of the systems. Beam quality in the form of near and far field images are obtained for most of our systems and incorporated into our final acceptance test before leaving the factory, contributing to the total quality program we have initiated. Measurement of beam quality relies heavily on CCD cameras and supporting software that allow us to directly measure intensity profiles, pointing stabilities, and calculate M2 and Fresnel numbers.
