ORPHEUS-ONE is an optical parametric amplifier designed for the infrared spectral range. It has fewer wavelength extension options but provides higher conversion efficiency into mid-IR compared to ORPHEUS-HP. While ORPHEUS-ONE is simple and efficient, the output spectral bandwidth is limited by the pump pulses. For sum-frequency generation (SFG) spectroscopy and other applications requiring broad-bandwidth infrared pulses – consider ORPHEUS-MIR.
