Mid-ir microchip laser: zns:cr2+ laser with saturable absorber material

Abstract From the Canadian patent

A laser includes a substrate formed of a II-VI semiconductor material grooves , formed at an , input end of the substrate and input fibers that engaged to the grooves to receive multiple input , optical beams of pump light. The laser further includes optical waveguides formed in the , substrate that are respectively coupled to the input fibers where one , waveguide corresponds to , one input fiber and where the optical waveguides extend to an output end of the substrate to , form multiple output optical ports. Additionally the laser includes a laser , gain region doped with transitional metal ions in the substrate that overlap with the optical waveguides near the , output optical ports …
