ORPHEUS-PS is a narrow-bandwidth optical parametric amplifier (OPA) designed for use with PHAROS and CARBIDE lasers. The device is pumped by picosecond pulses generated in a second harmonic bandwidth compressor SHBC and seeded by a white-light continuum generated by femtosecond pulses. This configuration enables high pulse-to-pulse energy stability compared to other methods for generating tunable picosecond pulses. The white-light generation and amplification are integrated within a single housing, delivering high long-term stability and ease of use.

ORPHEUS-PS features high conversion efficiency, bandwidth- and diffraction-limited output, and full computer control, making it a robust and user-friendly solution for advanced applications.

Additionally, part of the pump laser radiation can be split to simultaneously pump a femtosecond OPA alongside the ORPHEUS-PS narrow-bandwidth OPA. This enables access to a complete set of beams for versatile spectroscopy applications, including femtosecond stimulated Raman spectroscopy (FSRS) and sum-frequency generation (SFG) spectroscopy.

Applications

Femtosecond stimulated Raman spectroscopy (FSRS)
Sum-frequency generation (SFG) spectroscopy
