Overview

ORPHEUS‑N is a non-collinear optical parametric amplifier (NOPA) pumped by a Ytterbium-based femtosecond laser amplifier. 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 the 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 the 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 one ORPHEUS‑N systems can be operated simultaneously with a single amplifier providing several pump and/or probe channels with independent wavelength tuning.
