摘要：
Bleaching relaxation in PbS-quantum-dots-doped phosphate glasses in dependence on the dot size is presented. The fast bleaching decay component is increased from 14 to 93 ps as the dot size increased from 4.7 to 5.8 nm. The glasses are employed as saturable absorbers for mode-locking and Q-switching of 1.3 mum neodymium lasers. Q-switched pulses of 120 ns (0.1 muJ) in duration (energy) and the average output power of 3 mW from diode-pumped Nd3+:KGW laser and ultrashort pulses of maximum 250 muJ in energy and 150 ps in duration from a Nd3+:YAP laser were obtained.
