ABSTRACT:
A visible laser source comprises a sub mount. A semiconductor laser located on the sub mount has an active layer formed at a surface of the semiconductor laser. The active-layer formed surface of the semiconductor laser opposes the sub mount. An optical nonlinear device located on the sub mount has a waveguide formed at a surface of the optical nonlinear device. The waveguide formed surface of the optical nonlinear device opposes the sub mount. The semiconductor laser and the waveguide are directly coupled to each other for direct application of a fundamental wave from the semiconductor laser to the optical nonlinear device.
