Abstract
We present a 'loss balance' criterion to estimate the proper gain medium length (PGML) of the pulsed Ti:Sapphire laser under high pump level and optimal output coupling conditions according to the gain-loss character of pulsed Ti3+:Al2O3 laser longitudinally pumped by a pulsed laser beam, it was proved by several examples, and high efficiency was obtained. In one-longitudinally-pumped Ti3+:sapphire laser, the PGML 1 is determined by the equation: e-(alpha (p)1) plus e-(alpha (p)1/3) equals 1, where (alpha) p is the absorption coefficient to the pump beam, (beta) is the figure of merit (FOM value) of the crystal. When dual-longitudinally- pumped, the PGML is L less than or equal to 2l/3.
