Built-in Second Harmonic Generator

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 redinfrared range (620–2700 nm). To further enhance its wavelength tuning capabilities, the OPA can be equipped with an optional harmonics. The result is straightforward access to a broad, gap-free wavelength range from UV to the mid IR (210 nm – 16 μm).

Factory Optimized Pump Pulse Energies

The Spirit-OPA 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 multibeam, multi-color time resolved experiments. The Spirit-OPA-30 is optimized for high power application and can be pumped with up to 30 W.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™ and Solstice®ultrafast amplifiers.
