Abstract

We report on first demonstrations of ${\mathrm{CdSiP}}_2$-based optical parametric oscillators that are pumped by eye-safe $Q$-switched nanosecond laser sources operating at 1.57 μm. One device reached 40% optical conversion efficiency generating 10 mJ of energy near degeneracy in the 3 μm region. Angle tuning of a similar device through the middle infrared was demonstrated with the signal and idler waves being tuned from 2.28 μm to 5.05 μm.
