Abstract:
In this work three different concepts for micro integrated laser sources emitting light at 560 nm are investigated. The modules have different near infrared diode laser sources and different geometries of the crystals for second harmonic generation. The power emitted by the modules varies from 112mW achieved with a simple module with a ridge-waveguide laser and a ridge-waveguide crystal to 548mW coming from a module using a laser with subsequent amplifier and a planar-waveguide crystal. The article features a detailed description of the near infrared sources and the used crystals as well as the discussion of the complete modules.
