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

ORPHEUS-MIR serves as an excellent high-repetition-rate source for spectroscopy, such as two-dimensional infrared (2D IR) and vibrational sum-frequency generation (SFG) spectroscopy. Combined with a narrow-bandwidth output of SHBC, it forms a compact laser system for SFG measurements, covering most of the MIR spectrum in a single shot and providing high spectral resolution. In addition, its high output stability is the key to fast and high-quality SFG imaging.

Furthermore, for MIR applications requiring CEP-stable pulses, ORPHEUS-MIR provides unique CEP-stable option in the complete 2500 – 15000 nm range.
