Investigation of dye lasers pumped by high-power KrF laser radiation
Abstract
The lasing characteristics of ethanol solutions of rhodamine R6Zh, coumarin K47, PTP and POPOP dyes excited by radiation from a KrF laser at approximately 10 J with pulse lengths of approximately 80 nsec were investigated. Lasing energy of approximately 1.1 J with efficiency of approximately 14% was obtained for R6Zh and K47 solutions; the energy for PTP was 0.65 J, with efficiency of approximately 8%; the respective figures for POPOP were 0.3 J and 5%. The advantages and disadvantages of a number of dye laser cells designed to be pumped by high power excimer lasers were investigated experimentally.
