Overview

ORPHEUS and ORPHEUS‑ONE are collinear optical parametric amplifiers of white light continuum pumped by femtosecond Ytterbium based laser amplifiers. With the additional feature of being able to work at high repetition rates, ORPHEUS maintains the best properties of TOPAS series OPA‘s: high output pulse stability throughout the entire tuning range, high output beam quality and full computer control via USB port as well as optional frequency mixers to extend the tuning range from UV up to mid IR ranges.

ORPHEUS provides tunable OPA output (630 – 2600 nm) with residual second harmonic (515 nm) and fundamental radiation (1030 nm) beams at the same time.

While ORPHEUS‑ONE provides OPA output at (1350 – 4500 nm) Signal and Idler. The extended range 4500 – 16000 nm is accessed by mixing the signal and idler of the second stage in a mid IR crystal. In comparison to standard ORPHEUS + DFG configuration, the ORPHEUS‑ONE provides higher conversion efficiency into the infrared range.

Femtosecond pulses, high power tunable output together with flexible multi kilohertz repetition rate make the tandem of PHAROS and ORPHEUS an invaluable tool for multiphoton microscopy, micro structuring and spectroscopy applications. Several ORPHEUS can be pumped by single PHAROS laser providing independent beam wavelength tuning.
