Zinc-indiffused MgO:PPLN waveguides for blue / UV generation via VECSEL pumping
We present the design and characterisation of a zinc-indiffused periodically poled lithium niobate ridge waveguide for second harmonic generation of ~390 nm light from 780 nm. We use a newly developed, broadband near-infrared vertical-external-cavity surface-emitting laser (VECSEL) to investigate the potential for lower footprint nonlinear optical pump sources as an alternative to larger commercial laser systems. We demonstrate a VECSEL with an output power of 500 mW, containing an intracavity birefringent filter for spectral narrowing and wavelength selection. In this first demonstration of using a VECSEL to pump a nonlinear waveguide, we present the ability to generate 1 mW of ~390 nm light with further potential for increased efficiency and size reduction.

Abstract

We present the design and characterisation of a zinc-indiffused periodically poled lithium niobate ridge waveguide for second harmonic generation of ~390 nm light from 780 nm. We use a newly developed, broadband near-infrared vertical-external-cavity surface-emitting laser (VECSEL) to investigate the potential for lower footprint nonlinear optical pump sources as an alternative to larger commercial laser systems. We demonstrate a VECSEL with an output power of 500 mW, containing an intracavity birefringent filter for spectral narrowing and wavelength selection. In this first demonstration of using a VECSEL to pump a nonlinear waveguide, we present the ability to generate 1 mW of ~390 nm light with further potential for increased efficiency and size reduction.
