A versatile high-average-power ultrafast infrared driver tailored for high-harmonic generation and vibrational spectroscopy

Abstract

We report on an ultrafast infrared optical parametric chirped‑pulse amplifier (OPCPA), pumped by a 200‑W thin‑disk Yb‑based regenerative amplifier at a repetition rate of 100 kHz. The OPCPA is tunable in the spectral range 1.4–3.9 μm, generating up to 23 W of < 100‑fs signal and 13 W of < 200‑fs idler pulses for infrared spectroscopy, with additional spectral filtering capabilities for Raman spectroscopy. The OPCPA can also yield 19 W of 49‑fs 1.75‑μm signal or 5 W of 62‑fs 2.8‑μm idler pulses with active carrier‑to‑envelope‑phase (CEP) stabilisation for high‑harmonic generation (HHG). We illustrate the versatility of the laser design, catering to various experimental requirements for probing ultrafast science.
