Abstract

We report on our latest developments in tunable ultra-violet (UV) light generation using compact diode-pumped Alexandrite lasers and zinc-indiffused MgO-doped PPLN waveguides. 376-393 nm is achieved via second-harmonic-generation (SHG) in Λ = 6.1 – 6.9µm PPLN waveguides (third-order SHG). A maximum UV output power of 1.3 mW from 185 mW throughput power is obtained showing potential for efficient and compact laser systems across a wide wavelength range in the UV.
