N2 - We report the first demonstration of an optical parametric oscillator based on the BaGa2GeS6 (BGGS) crystal pumped by nanosecond pulses at 1.064 μm. The developed system generated coherent radiation in the mid-infrared range with a tunable idler wavelength spanning from 3.4 μm to 12.5 μm. A maximum idler pulse energy of 0.73 mJ was achieved at 6.5 μm with a pump energy of 15.9 mJ, corresponding to a pump-to-idler conversion efficiency of 4.7 % and a quantum efficiency of 29 %. The tuning behavior showed good agreement with the theoretical Sellmeier predictions above 5 μm, while deviations exceeding 1° were observed below 4.5 μm. These results highlight the BGGS crystal as a promising nonlinear material for broadband tunable mid-IR generation under nanosecond pumping.
