Abstract
We firstly demonstrated a tunable 2.1 µm pumped mid-infrared type-II phase-matching ${{\rm BaGa}_4}{{\rm Se}_7}$ (BGSe) optical parametric oscillator (OPO). A signal tuning range of 3.82–3.99 µm was achieved. With a signal light produced by the BGSe OPO serving as seed, the ${{\rm ZnGeP}_2}$ (ZGP) optical parametric amplifier (OPA) was first introduced. A 4.35 W mid-infrared laser was obtained in the novel type-II BGSe OPO with a ZGP OPA system, which was pumped by a 24 W 1 kHz ${Q}$-switched Ho:YAG laser. The beam quality factor ${M^2}$ of the whole system is ${\sim}{2.3}$, which is over a 50% promotion on the previous ${M^2}$ results of single BGSe OPO.
