Abstract

A microsystem excitation light source emitting at 488 nm is presented. A direct single-pass nonlinear frequency conversion using a diode laser emission at 976 nm and a periodically poled lithium niobate waveguide crystal for efficient second-harmonic generation is demonstrated. This was realized on a micro-optical bench with a combined thermal management and a footprint of ( 25 mm × 5 mm ) . At 217 mW fundamental power a generated power of 56 mW at 488 nm with a conversion efficiency of 26% was achieved. With a power stability below 1%, this wavelength stabilized compact device is well suited for Raman spectroscopy.
