  • Optional narrowband extension up to 15000 nm

Overview

ORPHEUS-MIR is a versatile system optimized for the efficient generation of broadband mid-IR pulses. In general, it is a two-channel optical parametric amplifier (OPA), followed by a difference frequency generation (DFG) stage. The system provides broadband pulses in the tuning range of 2.5 – 11 μm and reaches up to 15 μm with optional narrowband extension. Signal and Idler outputs are available simultaneously, but they are a Signal-Idler pair; thus, their wavelengths are linked. The system architecture is well-suited for high energy and high power PHAROS and CARBIDE lasers.

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 strong-field physics applications
