PbS (Se)-Doped Glasses as Passive Q-Switches for 1.5-µm Er: Glass and 2.1-µm Ho: YAG Lasers

摘要: Passive Q-switch operation of PbS-and PbSe-doped glasses as saturable absorbers for Er: glass and Ho: YAG lasers was demonstrated. Pulses of 110 ns in duration and 0.2 mJ in energy at 1.54 µm as well as 60 ns and 22 mJ at 2.1 µm were generated without intracavitv focusing.
