Millisecond Pulse Generating System for a Continuous Wave C02 Laser.

Abstract

A system has been developed for generating single millisecond pulses and pulse trains with a continuous wave industrial CO2 laser while simultaneously measuring the corresponding irradiance with calorimeters that have a 0.5 5 response time. First area moment equations are derived and used to balance the inertia forces of a continuously variable angle chopper blade used in the system. The results of a study to determine calorimeter response time, investigate system accuracy, and demonstrate systems use are also presented.
