27 May 1998 Ultrashort-pulse generation in solid state dye lasers
Author Affiliations +
Generation of ultrashort pulses (picosecond range duration) in pyrromethene-580 (PM-580) and xanthene 11B dyes doped modified PMMA polymer lasers is reported. Active polymer elements were pumped by second harmonic radiation of the 50 picosecond Nd:YAG laser. A single-pulse and train-pulse laser generation was observed at different conditions (variable optical resonator length and pump energy) with a pulsewidth ranging from 140 ps to 30 ps. The train-pulse generation is attributed to mode-locking of a laser resonator. The lifetime (tau) e, of an excited quantum state of a laser transition of the PM- 580 dye molecules has been estimated ((tau) e equals 200 divided by 250 ps) from the pulse-train duration.
