We report the first demonstration of an ultra-wide tunable MIR optical parametric amplifier (OPA) based on a new nonlinear crystal, BaHgGeSe4 (BHGSe). Pumped by a picosecond (ps) 1.064 µm laser, the OPA achieves an unprecedented idler tuning range of 3–14 µm, with pulse energies of 176 µJ at 7.3 µm and 143 µJ at 11.8 µm, and pump to idler conversion efficiency of 2.15 and 1.74%, respectively.
