The aluminum and gallium contents of these crystals were measured; the amount of substitution and its distribution in one crystal and in the mass of crystals in a run were determined. Crystals grown by slow cooling were badly segregated with respect to aluminum and gallium content whereas gradient‐grown crystals were very uniform. 74) "Excited State Dynamics of Tm Ions in Yttrium Aluminum Garnets," Optical Materials 1, 11, () (with G.

The lattice and grain‐boundary diffusion coefficients of ytterbium, which substitutes for yttrium, have been determined in high‐purity, stoichiometric yttrium aluminum garnet (YAG) polycrystals in the temperature range °–°C, in air.
Ytterbium oxide thin films were produced on the YAG surfaces by a dipping method. The chapter starts with the properties of yttrium aluminum garnet (YAG) as a host for the Nd 3+ ion with lasing at mm, and the effects of changes in the garnet composition on the laser performance.
It then proceeds to 2 micron lasers, i.e., thulium and holmium doped crystals, emphasizing the various pumping modes such as diode pumping.
The excited Cr 3 + ions transmit their energy to Tm 3 + ions in a process called cross-relaxation. The cross relaxation is a near-resonant, nonradiative process in which a single TM 3 + ion in excited state generates two TM 3 + ions in the upper laser level (Quarles et al., ).
The output energy obtained from those types of lasers was in the. Techniques for spatial spectral holography include a doped crystal comprising Thulium doped into a host crystal of Yttrium Lutetium Aluminum Garnet wherein a concentration of Thulium atoms is less than 3 atomic percent.
