ORPHEUS-N is a non-collinear optical parametric amplifier (NOPA). Depending on the ORPHEUS-N model, it has a built‑in 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 pulses of less than 30 fs in the 700 – 850 nm range. ORPHEUS-N with a third harmonic pump (ORPHEUS-N-3H) delivers pulses of less than 30 fs in the 530 – 670 nm range.
An optional second harmonic generator is available, extending the tuning range down to 260 – 450 nm. Featuring a built-in pulse compressor, ORPHEUS-N is an invaluable instrument for time-resolved spectroscopy. A single PHAROS or CARBIDE laser can pump more than one OPA device providing several pump and/or probe channels with independent wavelength tuning.
