High Repetition Rate, Tunable Mid-Infrared BaGa<sub>4</sub>Se<sub>7</sub> Optical Parametric Oscillator Pumped by a 1 μm Nd:YAG Laser

High Repetition Rate, Tunable Mid-Infrared BaGa<sub>4</sub>Se<sub>7</sub> Optical Parametric Oscillator Pumped by a 1 μm Nd:YAG Laser

A tunable and compact mid-infrared optical parametric oscillator (OPO) based on BaGa<sub>4</sub>Se<sub>7</sub> (BGSe) crystal with a repetition rate up to 250 Hz was demonstrated. A high energy and more approachable side-pumped Q-switched Nd:YAG laser was employed as the pump...
