Orpheus-N Series - Non-collinear Optical Parametric Amplifier

ORPHEUS-N is a non-collinear optical parametric amplifier (NOPA) pumped by the PHAROS laser system. ORPHEUS-N works at repetition rates of up to 1 MHz. The device is equipped with computer controlled stepping motor stages, allowing automatic tuning of the output wavelength. An optional signal second harmonic generator is available extending the tuning range down to 250 - 450 nm.

ORPHEUS‑N is a non-collinear optical parametric amplifier (NOPA) pumped by the PHAROS laser system. Depending on the ORPHEUS-N model, it has a built in second or third harmonic generator producing 515 nm or 343 nm pump. ORPHEUS‑N with second harmonic pump (ORPHEUS‑N‑2H) delivers pulses of less than 30 fs in 700 – 850 nm range with average power of more than 0.5 W at 700 nm 1). ORPHEUS‑N with third harmonic pump (ORPHEUS‑N‑3H) delivers pulses of less than 30 fs in 530 – 670 nm range with average power of more than 0.2 W at 550 nm. ORPHEUS-N works at repetition rates of up to 1 MHz.

The device is equipped with computer controlled stepping motor stages, allowing automatic tuning of the output wavelength. An optional signal’s second harmonic generator is also available, extending the tuning range down to 250 – 450 nm. Featuring a state of the art built in pulse compressor ORPHEUS‑N is an invaluable instrument for time-resolved spectroscopy. More than two ORPHEUS‑N systems can be pumped with a single PHAROS laser providing several pump and/or probe channels with independent wavelength tuning.
