ORPHEUS-F is a hybrid optical parametric amplifier, combining the short pulse duration produced by a non-collinear OPA and the wide wavelength tuning range offered by a collinear OPA. The Signal pulses are tunable in a 650 – 900 nm wavelength range and can be compressed with a simple prism-based setup down to < 60 fs. The Idler pulses are tunable in a 1200 – 2500 nm tuning range and compressed down to 40 – 100 fs. Furthermore, an optional long-pulse mode is available for accessing the 900 – 1200 nm tuning range. Our non-collinear OPA ORPHEUS‑N‑2H produces broader bandwidths, is compressible down to < 20 fs, but has a limited tuning range of 650 – 900 nm, while the standard ORPHEUS provides longer pulses, 200 – 300 fs. Thus, for many applications, ORPHEUS-F is the optimal choice.
