Paper Abstract

Ultraviolet single mode laser light is proposed by frequency quadrupling the output of a Nd:YLF laser with two successive frequency doubling stages. For a simple linear cavity laser configuration investigated at 1312 nm, we have obtained an intracavity power of 310 W for 16 W of absorbed pump power (λp ~ 806 nm). Up to 10 mW tunable single-frequency laser (λ=656-658 nm) is observed. This has been achieved by intracavity second-harmonic generation of a diode-pumped Nd:YLiF4 linear laser oscillating on the σ-polarized 4F3/2-4I13/2 transition (λω ~1314 nm) with a β-Barium Borate (BBO) crystal. We also report the experimental measurement of the red-uv conversion efficiency according to the waist size in the BBO crystal. Obtained value is compared to those given by the Boyd-Kleinman theory.
