Ultrashort-Pulse VIS Optical Parametric Amplifier
- Ultrashort UV – VIS – NIR pulses
- < 50 fs pulse duration at 500 nm
- Up to 100 kHz repetition rate
- Up to 20 W, 1 mJ pump
- Optional UV extension down to 250 nm
ORPHEUS-VIS is an optical parametric amplifier (OPA) designed for generating high-energy, short-pulse output in the visible (VIS) spectral range. The system provides ultrashort pulses tunable across 450 – 600 nm or 320 – 900 nm, depending on the selected configuration, and can be extended down to 250 nm with an optional UV extension.
ORPHEUS-VIS is compatible with CARBIDE or PHAROS femtosecond pump lasers, supporting up to 20 W average power and 1 mJ pulse energy, thus it provides output in the tens of microjoules in the VIS range and microjoule-level output in the UV range.
ORPHEUS-VIS is an excellent high-repetition-rate source for ultrafast spectroscopy techniques, including two-dimensional electronic spectroscopy (2DES), time-resolved photoemission spectroscopy, and a wide range of other applications within the visible spectral range.
