| 摘 要： | Cr^4＋ ion with tetrahedral symmetry, as found in single crystals of forsterite and YAG, have found application as saturable-absorbors, tunable solid state lasers etc. However, a high concentration of active Cr^4＋ species is difficult to obtain because it is rather unstable in these materials. It is expected that the continuing search for other ahernative hosts will lead to the emergence of new efficient Cr^4＋ -doped lasers.
