Affect of High-Temperature Oxidizing Annealing on Spectroscopic Characteristics of Cr:Mg2SiO4 Laser Crystals Grown in Different Conditions

The evolution dynamics of spectroscopic characteristics of Cr:Mg₂SiO₄ laser crystals grown in different conditions under the prolonged high-temperature oxidizing annealing of these crystals have been studied and analyzed. Such annealing can substantially enhance the characteristics of the crystals, however, behavior of the crystals during the annealing drastically depends on the preliminary growth conditions.
