SYSTEM AND METHODS FOR SPECTRAL BEAM COMBINING OF LASERS USING VOLUME HOLOGRAMS

摘要

Volume holographic gratings are used to spectrally combine the emissions from multiple sources into a single output beam. Transmission of reflection gratings are utilized with either laser diode bars, fiber lasers, or fiber collimated light sources. The volume holographic spectral combiner can also be used to feedback and stabilize the wavelength of the sources in an external cavity configuration.
