A two-species laser model with excitation energy transfer
Abstract
A theoretical model is proposed for a laser system with two types of active ingredients--one with three energy levels that is capable of population inversion and a second that transfers energy to the former to aid in this inversion. Some properties of the model are examined under continuous-wave and Q-switched operations, to establish a theoretical insight regarding the behavior of multiply doped systems such as LiYF4 doped with Ho, Tm, and Er. Concentration, temperature, and cavity Q dependences are introduced in simple, nontrivial ways, but are not fully explored in this preliminary report.
