摘　　要：We demonstrate a Fe:ZnSe laser gain-switched by a 2.9 m ZnGeP2 optical parametric oscillator under pulse repetition frequency of 1 kHz at liquid nitrogen temperature of 77 K. The maximum output power is 63 m W with pulse duration of 34.4 ns. The wavelength covers 3686.6–4088.6 nm and centers at 3897.7 nm. The output power decreases with increasing the temperature of the crystal in 77–222 K.We demonstrate a Fe:ZnSe laser gain-switched by a 2.9 m ZnGeP2 optical parametric oscillator under pulse repetition frequency of 1 kHz at liquid nitrogen temperature of 77 K.
