| Abstract: | Amplified luminescence is examined for a polished cylindrical rod. Nonlinear transport equations are used to examine the distribution of the emission along the rod and the mean density of the amplified luminescence. It is found that the probability of luminescence-induced transitions is of the same order as that for spontaneous transitions for a ruby rod. Calculations are presented for storage in a metastable level and for oscillation. Estimates are presented for the amplified luminescence from a cylinder with nonreflecting surfaces and also for a sphere.I am indebted to B. I. Stepanov for interest and valuable advice. |
