“…[4] Up to now, the HF lasers and xenon flash lamp pumped Er:YAG lasers have been the primary pumps for the high energy Fe:ZnSe lasers while the other pumps generated the Fe:ZnSe lasers with the output energy of several millijoules or less. [4] The HF lasers are usually employed as the pumps for short-pulseduration Fe:ZnSe lasers at room temperature, [5][6][7][8][9][10][11][12] and the Fe:ZnSe lasers and the pump both have the pulse durations of 100 ns-200 ns. For high energy Fe:ZnSe lasers with long pulse duration, the free-running 2.94-µm Er:YAG lasers at low temperature are the efficient pumps which have the pulse durations of several hundreds of microseconds.…”

We demonstrated an Fe:ZnSe laser pumped by a 2.93- μ m Cr, Er:YAG laser at liquid nitrogen and room temperature in single-shot free-running operation for the first time. The xenon flash lamp pumped Cr, Er:YAG laser had a maximum single pulse energy of 1.414 J, and the threshold and slope efficiency were 141.70 J and 0.70% which were respectively reduced by 29.3% and increased by 52.2% compared with the Er:YAG laser. At liquid nitrogen temperature of 77 K, the maximum single pulse energy of the Fe:ZnSe laser was 197.6 mJ, corresponding to a slope efficiency of 13.4%. The central wavelength and full width at half maximum (FWHM) linewidth were 4037.4 nm and 122.0 nm, respectively. At room temperature, the laser generated a maximum single pulse energy of 3.5 mJ at the central wavelength of 4509.6 nm with an FWHM linewidth of 171.5 nm.
