Abstract

A Dy:KPb2Cl5 (KPC) laser oscillating at approximately 4.4 µm under diode laser pumping at 1.7 µm is demonstrated for the first time. A maximum output pulse energy of 1.1 mJ was achieved at 10 mJ of absorbed pump energy. Tunable laser oscillation in the 4.2–4.5 µm spectral range was recorded with this crystal. Limitations of Dy:KPC for laser oscillation due to its challenging thermo-optical properties are discussed. This crystal is a further addition to the range of low-phonon-energy materials doped with Dy ions that can be applied for laser oscillation in the mid-infrared spectral range under direct diode laser pumping.
