We demonstrate a gain-switched Fe∶ZnSe laser pumped by a 2958nm pulsed Ho,Pr∶LLF laser.The maximum single pulse energy is 16.4μJ with a minimum pulse duration of 13.9ns at the pulse repetition frequency of 1 Hz when the Fe∶ZnSe crystal is cooled to 77K by liquid nitrogen,corresponding to a slope efficiency of 22.9％.The central wavelength and FWHM linewidth are 3957.4nm and 23.2nm,respectively.The output energy monotonically decreases as the crystal temperature increases in the range 77-293 K.
