High Pulse Energy, Narrow Linewidth 6.45 μm from an Optical Parametric Oscillator in BaGa<sub>4</sub>Se<sub>7</sub> Crystal

This paper presents a high pulse energy, narrow linewidth, mid-infrared (MIR) laser at 6.45 μm, based on a BaGa<sub>4</sub>Se<sub>7</sub> (BGSe) crystal optical parametric oscillator (OPO) pumped by 1.064 μm laser. The maximum pulse energy at 6.45 μm was up to 1.23 mJ, with a...
