FEATURES

ᰋ Ultrashort UV – VIS – NIR output
ᰋ < 50 fs pulse duration at 500 nm
ᰋ Up to 100 kHz repetition rateᰋ Up to 20 W, 1 mJ pump

ᰋ Optional UV extension down to 250 nm

and 1 mJ energy pulses, thus capable of providing up to tensof microjoules in VIS and microjoule-level output in UV.

ORPHEUS-VIS is an optical parametric amplifier (OPA)
optimized for the generation of high-energy short-pulse VISoutput. The laser system provides ultrashort pulses in thetuning range of 450 – 600 nm or 320 – 900 nm, dependingon the chosen configuration, and reaches down to 250 nmwith optional UV extension. The ORPHEUS-VIS system canbe coupled with PHAROS or CARBIDE femtosecond pumplasers and can be pumped with up to 20 W average power

ORPHEUS-VIS serves as an excellent high-repetition-ratesource for ultrafast spectroscopy such as two-dimensional
electronic spectroscopy (2DES), time-resolved photoemission
spectroscopy, and many other applications in the visible
spectral range.
