ease of use. The system features high conversion efficiency,
bandwidth- and diffraction-limited output, and full computer
control.
Part of the pump laser radiation can be split to simultaneously
pump a femtosecond OPA, giving access to the complete set ofbeams necessary for versatile spectroscopy applications suchas femtosecond stimulated Raman spectroscopy (FSRS) andsum-frequency generation (SFG) spectroscopy.

Pulse energy, µJ

ORPHEUS-PS is a narrow-bandwidth optical parametricamplifier (OPA), designed for PHAROS and CARBIDE lasers. The
device is pumped by picosecond pulses produced in a second
harmonic bandwidth compressor SHBC and is seeded by awhite-light continuum generated by femtosecond pulses. This
enables very high pulse-to-pulse energy stability comparedto other methods for generating tunable picosecond pulses.
The white-light generation is integrated into the same housingas the amplification, enabling high long-term stability andOutput power, mW
