| Abstract: | Cr-doped lasers, based on forsterite and YAG, provide broadly tunable power in the 1.25-μm and 1.45-μm regions. Performance data on tuning range, pumping, output power, and thermal management for these lasers is reviewed. Potential new crystals for Cr4+ should have heavy atoms to reduce lattice phonon frequencies, a distorted tetrahedral cage for the Cr4+ ion, and possibly an octahedral site for Cr3+. Possible materials include monticellite and diopside |
