We report a high-average-power picosecond optical parametric oscillator (OPO) tunable in the mid-infrared (mid-IR) based on CdSiP2 synchronously pumped by an Yb-fiber laser at ~ 80 MHz repetition rate. Successful operation of this high-repetition-rate singly-resonant picosecond OPO has been enabled by the improved CSP crystal quality over a long interaction length. The OPO can be tuned across 1264–1284 nm...
We report the first picosecond mid-infrared source based on OP-GaP using single-pass DFG, providing tunable radiation across 3040–3132 nm, with 57 mW of average-power at 3044 nm, 3.2% rms stability over 1h, in good beam-quality.
We report the first high-repetition-rate picosecond OPO based on CdSiP2, tunable across 6205–6695 nm in deep-IR, providing 105 mW at 6205 nm at 79.5 MHz, with 2.3% rms passive power-stability over 12h in high beam-quality.
High-average-power high-repetition-rate picosecond sources at wavelengths >5 mm in the deep-infrared (deep-IR) are interesting for variety of applications in spectroscopy and medicine [1]. In the absence of conventional ultrafast lasers, synchronously-pumped optical parametric oscillators (OPOs) offer a viable approach to the generation of ultrashort pulses in the deep-IR [2]. In the high-repetition-rate...
We report a stable picosecond ultraviolet source based on single-pass walk-off compensation scheme in BBO, providing up to 2.9 W of average UV power at ∼80 MHz repetition rate in high beam quality.
