Using a model for the quasi-three-level laser dealing with Gaussian waves, taking into account the saturation of the pump, the stimulated emission at the pump wavelength, the variation of the pump and laser waists along propagation (important for laser diode pumping) and the variation of the laser intensity along propagation, we evaluate the more promising -doped crystals for laser applications: , , , , , -, -, , , , , , . Our evaluation, established for the oscillator regime, differs from that of Deloach and coworkers valid for ns pulse extraction mode. , and are found to be the most efficient when considering the laser extracted power and -, -, , and are the most efficient when considering the small-signal gain of the amplifier regime.
