ORPHEUS-MIR is an optical parametric amplifier (OPA) designed for the efficient generation of broad-bandwidth mid-IR pulses. The laser system provides ultrashort pulses in the tuning range of 2.5 – 10 μm, extendable to 15 μm using a narrow-bandwidth extension. Due to its novel system design, ORPHEUS-MIR provides pulses with durations of <100 fs directly at the output, with Signal and Idler outputs available simultaneously. The system architecture is optimized for high-energy and high‑power CARBIDE and PHAROS femtosecond pump lasers.

ORPHEUS-MIR serves as an excellent high-repetition-rate source for advanced spectroscopic applications, including two-dimensional infrared (2D IR) and vibrational sum-frequency generation (SFG) spectroscopy. When combined with the narrow-bandwidth output of SHBC, it forms a compact laser system for SFG measurements, covering most of the mid-IR spectrum in a single shot while providing high spectral resolution. Its high output stability ensures fast and high-quality SFG imaging.

For mid-IR applications requiring CEP-stable pulses, ORPHEUS-MIR offers a unique CEP-stable option across the entire 2500 – 15000 nm range.

Applications

Broadband vibrational sum-frequency generation (SFG) spectroscopy
Time- and angle-resolved photoemission spectroscopy (TR-ARPES)
Two-dimensional infrared (2D IR) spectroscopy
High-harmonic generation (HHG) in solids
Other infrared spectroscopy and high-energy physics applications
