Abstract

We reported continuous-wave 528mW at 532nm from a compact visible-laser module. The green light was achieved from single-pass second harmonic generation with a periodically poled MgO-doped lithium niobate planar waveguide. For frequency-doubling, a distributed Bragg reflector (DBR) tapered laser diode having a single-frequency spectrum and watt-level power was used as a pump source. The highest conversion efficiency of 18.7% and power stability of 5% for a 1 hour period were attained from a compact laser module.
