- Up to 100 kHz repetition rate
- Completely computer controlled
- Built on well known TOPAS-800 OPA basis
ORPHEUS‑PS is a narrow bandwidth optical parametric amplifier of white light continuum, designed for Pharos / Carbide pump laser. This device is pumped by the picosecond pulses produced in SHBC‑515 (see options tab) narrow bandwidth second harmonic generator, and seeded by white light continuum generated by femtosecond pulses. This enables to achieve very high pulse to pulse stability compared to other methods of generating tunable picosecond pulses. The white light generation module is also integrated into the same housing as amplification modules, enabling even better long term stability and ease of use. The system features high conversion efficiency, nearly bandwidth and diffraction limited output, full computer control via USB port and LabVIEW drivers.
A part of the Pharos / Carbide laser radiation can be split to simultaneously pump a femtosecond OPA, providing broad bandwidth 630 nm – 16 µm tunable pulses, giving access to the complete set of beams necessary for versatile spectroscopy applications, for example narrow band Raman spectroscopy measurements, or surface sum-frequency spectroscopy.

Second Harmonic Bandwidth Compressor SHBC-515
This device is required to pump Orpheus-PS with PHAROS / CARBIDE femtosecond laser. It is dedicated for the formation of narrow bandwidth picosecond pulses from broadband output of ultrafast laser.
In PHAROS / CARBIDE platform SHBC is used to create flexible setups providing fixed wavelength or tunable narrow bandwidth ps pulses in combination with tunable wavelength broadband fs pulses. This feature is used in spectroscopy applications for mixing of wide and narrow bandwidth pulses such as sum frequency spectroscopy (SFG).
