Transition-metal-doped II-VI semiconductor materials enable high power lasers in the mid-infrared range and combine superb ultra-fast laser capabilities with high nonlinearity and polycrystalline microstructures that provide random quasi-phase matching. A femtosecond polycrystalline Cr:ZnS and Cr:ZnSe laser with a flexible design was developed by the authors; this figure shows the microstructure of polycrystalline Cr:ZnS, which is optimized for high SFH output.
