Power enhancement of continuous ultraviolet lasers

Abstract
High‐power cw laser radiation from nine Ar and five Kr laser transitions in the spectral range 275 <λ<365 nm has been generated in a highly ionized low‐pressure dc discharge. The output increases without saturation up to the maximum available discharge current of 480 Å. The most intense emission is 61 W obtained from the combined 351.1‐ and 363.8‐nm Ar III lines.
