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 optained an intracavity power of 310 W for 16 W of absorbed pump power (λ_p ~ 806 nm). Up to 10 mW tunable single-frequency laser (λ_2W = 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 ⁴F_3/2-⁴I_13/2 transition (λ_w ~ 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. Optained value is compared to those given by the Boyd-Kleinman theory.
