摘要：

By using a PbS-doped phosphate glass as an intracavity saturable absorber, we achieved passive Q switching of a 1.54-mu m Er:Yb:glass laser. We obtained Q-switched pulses with 110-ns duration and 0.2-mJ energy. The saturation intensity at 1.54 mu m was estimated to be similar to 60 kW/cm(2). (C) 2000 Optical Society of America.
