Abstract

A variable linewidth high-power TEA CO2 laser, utilizing a multiple-prism beam expander in conjunction with a Littrow-mounted grating, is described. Linewidths of ∼250-MHz (FWHM) at a total output energy exceeding 250 mJ have been obtained at the P20 (00°1—10°0), λ = 10.59-μm line. Laser linewidths can be varied continuously in the 250–650-MHz range for a corresponding change in output energy from 250 to 400 mJ. The present frequency selectivity method, which employs ZnSe prisms, can be applied directly to considerably higher-power CO2 lasers.
