Tunable ultraviolet laser source based on solid-state dye laser technology and CsLiB_6O_10 harmonic generation

Abstract

Tunable UV radiation centered at 289 nm was obtained from a 532-nm Nd:YAG pumped high-brightness solid-state dye laser, frequency doubled in CsLiB₆O₁₀. Frequency doubling to 284–294 nm was demonstrated from a singly doped, rotating pyrromethene dye plastic disk with damage threshold $>3\mathrm{J}/\mathrm{cm}{}^2$. UV energies up to 44 mJ at 10 Hz were obtained with a 15% absolute conversion efficiency from 532 nm.
