  • Abstract
    By varying the composition of a series of germanium garnets, it is possible to change the lattice constant of the structure over a wide range, and thus the crystal field. Three Cr-doped germanium garnets (Ca3Al2Ge3O12, CaY2Mg2Ge3O12, and MgY2Mg2Ge3O12) have been grown as single crystals. Spectroscopic results show that in these garnets the broad-band emission at room temperature is so strong that it totally dominates the R -line emission. The spectral region covered by emission from these crystals is from 700 nm to more than 1 μm. The room-temperature lifetimes range from 50 to 290μs.
