We demonstrate a novel traveling-wave-type optical parametric generator based on 1.25-mu m pumping of HgGa2S4 that produces tunable, high-power, transform-limited proportional to 200-fs pulses in the mid-IR from 5 to 9 mu m. Output idler energies on the microjoule level are obtained with maximum conversion efficiency of 11% for the amplifier stage, which is more than two times better than the results obtained with an analogous sample of the widely spread material AgGaS2.
