Dye stability under excimer-laser pumping

II. Visible and uv dyes


The stability of laser dyes under the excitation of a XeCl-laser (308 nm) has been investigated. The measurements were performed in an oscillator amplifier device where the amplifier was fully satured. This allows the comparison with the theoretical model showing that the main reason for dye degradation is the absorption of photo-products. Results for the most important dyes are presented. Dye stabilities range from 46 (fluorescein 27) to 3.4×104 (QUI) absorption processes per molecule before the dye solution has degraded to 1/2 of its initial energy output.
