Single frequency solid state laser

Patent ·
OSTI ID:6763326
This patent describes a solid state laser having a single longitudinal mode output at a selected laser output wavelength. It comprises: a block of solid state laser material having a cavity-forming mirror coating on one of two opposing faces, a pumping source for providing pump radiation at a wavelength such that its absorption depth in the block of solid state laser material is less than the dephasing; distance in the block of solid state laser material at the selected laser output wavelength divided by 2{pi}. The cavity-forming mirror having a high reflectivity at the selected laser output wavelength and a high transmissiveness at the wavelength of the pump radiation, means for collecting the pump radiation emitted from the pump source and for directing it into the one of the opposed ends of the block of solid state laser material having the cavity-forming mirror coating, and an output coupler optically aligned with the block of solid state laser material.
