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.
