Abstract
Absorption saturation as well as bleaching relaxation of 4A2 yields 4T1(4F) transition of tetrahedrally coordinates Co2+ ion in magnesium-aluminum and magnesium-gallium-aluminum glass ceramics prepared under different conditions were studied. Ground state absorption cross sections at the wavelength of 1.54 mm were estimated. The level of unsaturable losses was observed to be proportional to the cobalt concentration in the raw materials. The difference spectrum of stimulated emission and excited state absorption under excitation in the 4A2 yields 4T1 (4P) transition of the tetrahedral Co ion was derived and analyzed.
