ORPHEUS-N is a non-collinear optical parametric amplifier (NOPA). Depending on the model, ORPHEUS-N has an integrated second- or third-harmonic generator producing a 515 nm or 343 nm pump, respectively. ORPHEUS-N with a second-harmonic pump (ORPHEUS-N-2H) delivers < 30 fs pulses in the 700 – 850 nm range. ORPHEUS-N with a third harmonic pump (ORPHEUS-N-3H) delivers < 30 fs pulses in the 530 – 670 nm range. Both have built-in prism-based pulse compressor. Furthermore, an optional second harmonic generator is available, extending the tuning range down to ultraviolet (UV) spectral range.

A single PHAROS or CARBIDE femtosecond laser can pump multiple NOPAs, providing pump and/or probe with independent wavelength tuning for your state-of-the-art experiments.

For broader tunability range, refer to ORPHEUS-F. For ultrashort pulses tunable around 500 nm, refer to ORPHEUS‑VIS.
