Investigation of dye lasers excited by high-power KrF laser radiation

An investigation was made of the lasing characteristics of ethanol solutions of the dyes rhodamine 6G (R6G), coumarin 47 (C47), p-terphenyl (PTP), and POPOP pumped by high-power KrF laser radiation (λ = 248 nm) pulses of up to 10 J energy and 80 nsec duration. A laser output energy of 1.1 J at an efficiency of 14% was obtained from the R6G and C47 solutions. The optical strength of the R6G and C 47 solutions at the pump radiation wavelength was determined. The construction of dye lasers pumped by high-power excimer laser radiation was considered.
