Abstract
A laser light source apparatus includes a laser diode, a first optical assembly having one or more lenses for generating a collimated laser beam from light emitted by the laser diode, a doped microstructured glass block configured to generate laser emissions at at least a first wavelength and a second wavelength when pumped by the collimated laser beam, an input beam lens for focusing the collimated laser beam onto an input surface of the microstructured glass block, an optical alignment assembly, an output light guiding assembly, and a housing for containing and supporting the optical alignment assembly and the output light guiding assembly.
