ORPHEUS-N is a non-collinear optical parametric amplifier(NOPA) pumped by the PHAROS laser system. Dependingon the ORPHEUS-N model, it has a built in second or thirdharmonic 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 withaverage power of more than 0.5 W at 700 nm*. ORPHEUS-N
with third harmonic pump (ORPHEUS-N-3H) delivers pulses ofless than 30 fs in 530 – 670 nm range with average power ofmore 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 timeresolved spectroscopy. More than two ORPHEUS-N systems canbe pumped with a single PHAROS laser providing several pump
and/or probe channels with independent wavelength tuning.
