Laser system with solid state fluorescent converter matrix having distributed fluorescent converter particles
This patent describes a laser system, the combination comprising: (a) an active laser element; (b) a light source associated with the laser for pumping the laser to produce coherent, monochromatic light; (c) means positioned between the laser element and the light source for increasing the optical efficiency of the system by converting at least a portion of the light from the source which falls outside of the laser pumping band into light in the pumping band including: (1) a solid state fluorescent converter element exposed on one side thereof to light from the source for spectrally shifting light outside of the laser pumping band into light in the pumping band; (2) the converter element comprising a matrix which is transparent to and transmit light from the source including light in the pumping band and which physically supports an aggregate of individual converter particles dispersed throughout the matrix, the individual particles absorbing light outside of the pumping band and reemitting a portion thereof as light in the pumping band. The dispersed particles is located in the matrix so as to concentrate the particles in a zone on the other side of the converter and located adjacent to the laser.
