Abstract

Carbon monoxide lasers, with axial or transverse fast flow configurations excited by dc, rf or microwave discharges, provide powerful and efficient sources of radiation in the 5-μm range of the spectrum for industrial uses.1-3 The fast axial flow configuration is optimum for medium power (1-3 kW) applications requiring good beam quality, and this paper describes a research laser set up to provide data specifically on lasers using a turboblower for gas circulation in a low pressure drop flow loop, with transverse rf discharge excitation of two gain sections. An efficient liquid nitrogen heat exchanger provides a wide range of gas inlet temperatures for optimization studies.
