We report on thefirst BaGa4Se7 nanosecond optical parametric oscillator pumped byQ-switched Nd:YLiF4 laser at 1053 nm. The oscillator exhibits a pump threshold energy as low as 0.25mJ.Midinfrared (MIR) idler wave tuning from2.6 μmto 10.4 μmis demonstratedwith an angle-tuned type-I (o-ee) y-cut sample, highlighting the superior performance of this novel large bandgap chalcogenide nonlinear crystal to generate tunable coherent radiation over its fullMIR transparency range (0.47–18 μm). The phase-matching data are used to identify themost accurate dispersion relations of this compound among three recently published Sellmeier equations. Damage thresholdmeasurements yielded values as high as 2.04 J cm at 100Hz pulse repetition rate, one of the largest among existingMIRχnonlinearmaterials.
