摘要

We demonstrate a Fe:ZnSe laser gain-switched by a ZnGeP<sub>2</sub> (ZGP) optical parametric oscillator (OPO) under the pulse repetition frequency (PRF) of 1 kHz at room temperature. The 2.9 μm signal light of the OPO is employed as the pump for the Fe:ZnSe laser. The maximum output power of the Fe:ZnSe laser is 58 mW with the pulse duration of 2.7 ns under the incident pump power of 280 mW, corresponding to a peak pulse power of 21.5 kW and an optical-to-optical efficiency of 20.7%. The spectrum of the Fe:ZnSe laser has a range of 4030.2-4593.6 nm with a dip in 4187.1-4340.4 nm due to the absorption of CO<sub>2</sub>.
