Mode stabilization of a high power laser via computer vision

A computer vision system which performs real-time mode control of a high powered CO 2 laser has been developed. The device continuously monitors the output beam to derive alignment data for the primary resonator optic. The technique ensures that the laser's intensity distribution is as uniform...

Description
Summary:A computer vision system which performs real-time mode control of a high powered CO 2 laser has been developed. The device continuously monitors the output beam to derive alignment data for the primary resonator optic. The technique ensures that the laser's intensity distribution is as uniform as possible. Valuable profile data and beam diagnostics are also generated by the system.
