Abstract
We present a theoretical model proving that upconversion and thermal q uenching of fluorescence strongly Limit small-signal gain in a CW pump ed Cr:LiSAF laser, We have a good agreement with experimental measurem ents of small-signal gain obtained with a new simple method, We have t hen optimized the gain in a Cr:LiSAF laser pumped by two 400-mW red di odes, The highest gain, 1.11 at 600 mW of absorbed pump power, is obta ined if the pump spot is circularized inside the crystal and if the Cr :LiSAF is pumped on both sides, In Q-switched operation, this laser pr oduces tunable pulses (up to 6.5 mu J at 10 kHz) between 800 and 900 n m.
