Abstract

In this work, a high-power laser source with single-mode fiber output in the green spectral range is presented. A ridge waveguide laser with a Distributed Bragg-Reflector (DBR-RWL) and a Tapered Amplifier (TPA) are used as a pump source for a Ridge Waveguide Periodically Poled Lithium Niobate (RW-PPLN) crystal. The whole setup fits into a butterfly housing with a footprint of only 76 mm × 44 mm. At an emission wavelength of 532 nm, an optical output power of hundreds of milliwatt in a single spectral mode with a spectral width of the order of 1 MHz is achieved.
