radiation can be focused to a small beam radius. Thus, in the volume of the
pumped region, the inversion can be high even at relatively low pump energies.
Coupled with a high effective stimulated emission cross section, gain in the
pumped volume can be high. By matching the mode radius of the Ti:A1,0,
