摘要：

Glass doped with PbS quantum dots is presented as a saturable absorber (SA) for a passive Q-switching of a diode-pumped 1.9 mu m Tm:KYW laser. Output pulses with energy of 44 mu J at a repetition rate of 2.5 kHz with an average output power of 110 mW were obtained. The Q-switching conversion efficiency was 33%. The absorption saturation intensity of the glass doped with PbS quantum dots with a mean radius of 5.2 nm at a wavelength of 2 mu m was measured to be 1.5 MW/cm(2).
