Widely tunable (2.6–10.4 μm) BaGa4Se7 optical parametric oscillator pumped by a Q-switched Nd:YLiF4 laser

Kolker, Dmitri; Kostyukova, N.; Boyko, A.; Badikov, V.; Badikov, D.; Shadrintseva, A.; Tretyakova, N.; Zenov, K.; Karapuzikov, A.; Zondy, Jean-Jacques (IOP Publishing, 2018)

We report on the first BaGa4Se7 nanosecond optical parametric oscillator pumped by Q-switched Nd:YLiF4 laser at 1053 nm. The oscillator exhibits a pump threshold energy as low as 0.25 mJ. Mid-infrared (MIR) idler wave ...
