Description
Summary:A single-mode laser with unidirectional longitudinal pumping by laser diodes with and a power of is studied. In the mode, the output laser power is with the optical efficiency (slope efficiency 63.3%), which, as far as we know, is the best result for lasers with longitudinal pumping at from one face of the active crystal. Estimates of thermal effects show that, using a crystal (length , diameter , dopant concentration 0.27 at%) with two undoped ends and bidirectional diode pumping with a total power of , one can obtain an output power of in the mode from one active element.
