摘要：
Characteristics of an Fe:ZnSe laser with a new pump scheme were presented. An Fe:ZnSe crystal was placed inside the cavity of the Er:YLF laser pumped by a bar of laser diodes (LD) emitting at 975 nm. The high power 2.66 mu m wave similar to 50 ns pulses were generated inside the cavity due to passive Q-switching of the Er:YLF laser by an Fe:ZnSe saturated absorber. These pulses pumped the Fe:ZnSe laser. As a result, the pulses with an energy of similar to 2 mu J at a wavelength around 4 mu m and time duration of about 50 ns were generated. The laser operated in periodic-pulsed pump regime at room temperature with a repetition rate up to 200 Hz. The Q-switching pulse repetition rate during the pump pulse ran up to 2.5 kHz.
