Abstract
A laser-medium in the form of a dielectric crystal or glass doped with tetravalent chromium. The dielectric crystals are of olivine-like structure such as germanates of formula (A) (RE)GeO.sub.4 where (A=Na or Li, RE=Y, Lu or Gd), crystals of willemite structure Zn.sub.2 (Si or Ge)O.sub.4 tetrahedral sites, or any other single-crystal or polycrystalline compound containing the (Si.Ge)O.sub.4 tetrahedra in its crystal lattice, such as Ca.sub.3 La.sub.2 (SiO.sub.4).sub.6 and crystals such as YAG (Y.sub.3 Al.sub.5 O.sub.12).
