First-order quasi-phase-matched blue light generation in surface-poled Ti:indiffused lithium niobate waveguides

摘要

We demonstrate efficient first-order quasi-phase-matched second-harmonicgeneration in a surface periodically poled Ti:indiffused lithium niobatewaveguide; 6 mW of continuous-wave blue radiation (wavelength = 412.6 nm) wasproduced showing the potential of surface domain inversion for efficientnonlinear waveguide interactions.
