Pump-tuned deep-infrared femtosecond optical parametric oscillator across 6-7 μm based on CdSiP2

We report on a high-power femtosecond optical parametric oscillator (OPO) at 80 MHz repetition rate, tunable across 6318–7061 nm in the deep-infrared (deep-IR) using pump wavelength tuning. The OPO, based on CdSiP2CdSiP2 (CSP), is synchronously pumped by a commercial Ti:sapphire-pumped femtosecond O...
