  1. Due to our continuous product improvements, specifications are subject to change without notice.
  2. Specified at 100 kHz repetition rate.
  3. Efficiency defined as OPA output power divided by Spirit pump power at the OPA input port.
  4. 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.
  5. Please contact Spectra-Physics for available options at lower or higher pump pulse energy levels.


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).

Compatible Power Sensors

To verify and analyze the output power of your Spirit-OPA laser, we recommend the Ophir 3A-PF-12 (7Z02720) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the website.  Other Ophir sensors and meters may also be suitable for the Spirit-OPA, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
