In the meeting, we will present the CW laser amplification properties of the high quality Fe:ZnSe crystals. A home-constructed 2.92-μm Er:YAP laser served as the pump source of the Fe:ZnSe. The seed light was provided by a commercially available, single-mode quantum cascade laser emitting at ~4 μm. Detailed amplification properties were studied for different signal power and lasing spectra. The results indicate that the cryogenically cooled Fe:ZnSe crystal could be a promising gain element for the CW laser amplifier at 4-5 μm wavelength band.
