High-power narrow-band dye laser pumped by a XeCl Joule exciplex laser

A laser system consisting of a high-power, narrow-band dye laser and a Joule XeCl laser (λ = 308 nm) with high output characteristics is described. The system can be tuned over the spectral interval 330–800 nm. The efficiency ranges up to 19% at an output energy of 75 mJ, a linewidth of 0.01 nm, a divergence of 1–2 mrad, and a service life of 10⁷ pulses for the active medium of the dye laser. The repetition frequency is 1–5 Hz.
