ORPHEUS is a collinear optical parametric amplifier (OPA). Coupled with a PHAROS or CARBIDE femtosecond laser, ORPHEUS emits femtosecond pulses tunable from ultraviolet (UV) to mid-infrared (MIR) at a repetition rate of up to 2 MHz. Thus, it is an invaluable tool for ultrafast spectroscopy, nonlinear microscopy, and microstructuring applications.

The ORPHEUS collinear OPA comes in three different configurations to perfectly match the customer needs. The basic ORPHEUS configuration is a cost-effective choice providing a wide and gapless tuning range from 630 to 2600 nm, which is extendable down to 210 nm with an external harmonic generator. If higher pump power and a higher-level of automation are desired, the ORPHEUS-HP configuration is your choice. It offers complete automation and integrates all of the wavelength extension options into a single thermally-stabilized housing. Its wavelength tuning is completely hands‑free and uses automated wavelength separation to ensure the same position and direction for the 190 – 2600 nm output. The spectral range is extendable up to 16 µm; thus, covering the entire spectrum from UV to MIR. Similar to ORPHEUS-HP, the ORPHEUS‑HE configuration brings the aforementioned automation but also accepts high pump pulse energy.
