Abstract

UV wavelength laser sources are an important area of research due to their use in atmospheric and atomic sensing; however, diode lasers at these wavelengths often have low power, poor spatial mode quality, and broad optical spectra. An alternative approach to a UV laser source is an IR diode laser with frequency conversion. In this work, a dual element ridge waveguide device is presented for third harmonic generation of UV wavelengths. This design has been successfully implemented to generate and sustain 3mW of UV from 200mW of IR pump in the waveguide.
