Abstract:

This document describes a high-repetition-rate TEA-CO2 laser system which operates in a closed loop and can produce an average output beam power in excess of 1.5 kW at 1 kHz. After a brief outline of the design concepts of this important installation, details are given of the various subsystems involved in the electrical excitation, circulation of gases and control of the optical cavity. Then follow operational characteristics and a description of the behavior of the multimodal beam of radiation. Despite some limitations due to deterioration of gases and thermally induced distortion of the output coupling window, this laser remains reliable and capable of operating continuously for relatively long periods of time. It is also a versatile tool, incorporating several features which make it safe to use. Author
