Abstract
We report accurate, direct measurements of the absorption recovery lif etimes (fluorescence lifetimes, tau(f)) Of dyes which are commonly use d as saturable absorbers in self-starting passively mode-locked Ti: sa pphire lasers. The values tau(f) for IR 140, HITCI, and DDI dissolved in ethylene glycol are respectively 165 +/- 5 ps, 200 +/- 7 ps, and 27 +/- 0.5 ps. The femtosecond temporal resolution available in these me asurements also made possible the determination, for the first time to our knowledge, of fast initial relaxation rates of the excited electr onic band of these dyes.
