Yb-fiber-pumped high-repetition-rate picosecond deep-infrared optical parametric oscillator

In conclusion, we have demonstrated the first high-repetition-rate picosecond OPO based on CSP tunable across 6205-6724 nm in the deep-IR. The OPO provides as much as 105 mW of deep-IR average idler power at 6205 nm, with more than 50 mW over >50% of the tuning range in high spatial beam quality. Complete characterization of the OPO including power scaling, power stability, and thermal effects will be presented.
