Abstract
Nd:YAG and a Nd:YAG-pumped dye laser are used to generate tunable deep ultraviolet radiation down to 240 nm in a lithium triborate crystal ( LBO) by noncollinear sum-frequency mixing. All longer wavelengths can be generated by a combination of harmonic generation of the dye laser and sum-frequency mixing, 240 nm being the near noncritical limit. A s et of versatile Sellmeier dispersion equations is derived to satisfact orily predict phase-matching in LBO.
