ORPHEUS-PS is a narrow-bandwidth optical parametric amplifier (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 a white-light continuum generated by femtosecond pulses. This enables very high pulse-to-pulse energy stability compared to other methods for generating tunable picosecond pulses. The white-light generation is integrated into the same housing as the amplification, enabling high long-term stability and 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 of beams necessary for versatile spectroscopy applications such as femtosecond stimulated Raman spectroscopy (FSRS) and sum-frequency generation (SFG) spectroscopy.
