The Spirit-OPA® is an automated collinear optical parametric amplifier (OPA) specifically built and optimized for the Spirit® ultrafast laser. The turn-key, high repetition rate Spirit femtosecond laser combines with the widely tunable Spirit-OPA family to create a powerful, user-friendly tunable source for high repetition rate ultrafast spectroscopy.
The Spirit-OPA includes a built-in second harmonic generator to convert the Spirit IR output into a 520 nm pump beam for the OPA, which then generates signal and idler in the red-infrared range (630–2600 nm). To further enhance its wavelength tuning capabilities, the OPA can be equipped with an optional harmonics module. The result is straightforward access to a broad, gap-free wavelength range from UV to the mid IR (210 nm – 16 μm).
The Spirit-OPA family can be factory optimized for a wide range of pump pulse energies (up to 120 μJ). This versatility allows for multiple configurations such as pumping a single OPA for maximum output energy or simultaneously pumping two or more OPAs for multi-beam, multi-color time resolved experiments. There are two Spirit-OPA versions available: The Spirit-OPA-8 which can be pumped with up to 8 W and the Spirit-OPA-30 which is specifically optimized for high power applications (up to 30 W pump power).
With its high repetition rate (100 kHz and above) and μJ level pulse energy, the Spirit family complements Spectra-Physics’ kHz, multi-mJ class Spitfire® Ace™ultrafast amplifiers.
