Spirit-OPA® High Repetition Rate Automated Optical Parametric Amplifiers
Overview
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.

Footnotes:
- Due to our continuous product improvements, specifications are subject to change without notice.
- Specified at 100 kHz repetition rate.
- Efficiency defined as OPA output power divided by Spirit pump power at the OPA input port.
- Spirit-OPA-8 and Spirit-OPA-30 pump parameters are determined at the time of order and factory set. Spirit-OPA can be factory optimized for one pump pulse energy level only.
- Please contact Spectra-Physics for available options at lower or higher pump pulse energy levels.
Features
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 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).
Factory Optimized Pump Pulse Energies
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).
