The rate consideration of relaxation transitions between sublevels of a multiplet in the generation spectrum of YAG:Nd-laser

Experimental technique and devices

The two alternative forms of the Tang - Statz - DeMars system of equations are presented in the paper. The spectra of the multimode generation of YAG: Nd +3-laser are calculated assuming the Boltzmann distribution over the sublevels of the 4F3/2 multiplet and a specific rate of cross-relaxation transitions between those sublevels. The results obtained are compared with experimental data.
