ORPHEUS is a collinear optical parametric amplifier (OPA) designed to provide the widest tuning range. Coupled with a PHAROS or CARBIDE laser, it emits femtosecond pulses tunable from ultraviolet to mid-IR at a repetition rate of up to 2 MHz. Accordingly, it is an invaluable tool for ultrafast spectroscopy, nonlinear microscopy, and microstructuring applications.

The base ORPHEUS model provides a tuning range from 630 to 2600 nm, which is extendable down to 210 nm with external harmonic generators. The ORPHEUS-HP model integrates all of the wavelength tuning options into a single thermally-stabilized housing. Output wavelength calibration and feedback is possible with an internal spectrometer. Its design offers completely hands-free wavelength tuning and automated wavelength separation, ensuring the same position and direction for the 190 – 2600 nm wavelength range. The mid-IR output is tunable from 2400 nm to 16 µm and has a separate output port. The ORPHEUS‑HE model is designed for higher pump pulse energy.
