Overview

ORPHEUS‑F is a hybrid optical parametric amplifier of white‑light continuum pumped by femtosecond Ytterbium based laser amplifiers. This OPA combines the short pulse durations that are produced by a non‑collinear OPA and wide wavelength tuning range offered by collinear version. The Signal beam can be easily compressed with a simple prism‑based setup down to < 60 fs in most of the tuning range, while Idler is compressed in bulk material down to 40 fs – 90 fs depending on wavelength.

It is possible to limit the output bandwidth to some extent (up to 2 – 3 times) without losing any output power. By comparison, standard ORPHEUS device uses spectral narrowing to produce bandwidth‑limited 200 fs – 300 fs duration pulses directly at the output, with extended Signal/Idler tuning range and options to generate ultraviolet and mid‑infrared light. Our non‑collinear ORPHEUS‑N‑2H device produces even broader bandwidths, compressible down to 20 fs, but limits the tuning range to 650 nm – 900 nm. This places the performance of ORPHEUS‑F configuration in between our other solutions.
