ORPHEUS-N is a non-collinear optical parametric amplifier (OPA), also know as NOPA. Depending on the model, ORPHEUS-N includes an integrated second- or third-harmonic generator, producing a 515 nm or 343 nm pump, respectively:

ORPHEUS-N-2H: A second-harmonic pump delivers <30 fs pulses in the 700–850 nm range.
ORPHEUS-N-3H: A third-harmonic pump delivers <30 fs pulses in the 540–660 nm range.

Both models feature a built-in prism-based pulse compressor. Additionally, an optional second-harmonic generator is available, extending the tuning range into the ultraviolet (UV) spectral region.

A single CARBIDE or PHAROS femtosecond laser can pump multiple NOPAs, enabling independent wavelength tuning for pump and/or probe beams for advanced experiments.

For a broader tunability range, refer to ORPHEUS-F broad-bandwidth hybrid OPA. For ultrashort pulses tunable around 500 nm, refer to ORPHEUS‑VIS.
