Abstract

We demonstrate Ultra-Violet (UV) light generation using a diode-pumped Alexandrite laser and its Second Harmonic Generation (SHG) via Zn-indiffused MgO:PPLN waveguides. A wavelength range of 375-393 nm is obtained using third order SHG in Λ = 6.1−6.9 μm poled waveguides. Up to 1.3 mW UV power is obtained from 185 mW throughput infrared power. We believe that the wavelength and transverse mode flexibility from these waveguides gives rise to a wide range of applications for an efficient and compact laser module in the UVA range.
