Footnotes:

  1. Due to our continuous product improvement program, specifications are subject to change without notice.
  2. When pumped with 40 µJ at 1040 nm. For other pump levels, please contact Spectra-Physics.
  3. Compressors for signal and/or idler are options.
  4. Spirit-NOPA pump parameters are determined at the time of order and are set at the factory.
  5. The Spirit-NOPA is a Class IV – High Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to the direct and reflected beams. Diffuse as well as specular reflections can cause severe skin or eye damage.

Spirit-NOPA-VISIR Peformance for 3-Photon Imaging

In combination with our industry-proven Spirit platform,the Spirit-NOPA-VISIR provides an ideal platform for 3-photon excitation microscopy. Spirit-NOPA-VISIR comprises two amplification stages. The first amplification stage is non-collinear, which generates broad bandwidth,and the second amplification stage is collinear, which enables a broad tuning range.

Spirit-NOPA-VISIR provides a broadly tunable output of ultrashort pulses with a tuning range of 650 nm to 900 nm (signal) and 1200 nm to 2500 nm (idler), including key wavelengths for deep-tissue, 3-photon imaging. Optionally, the signal output can be compressed down to <70 fs using an external prism-based compressor unit, and the idler output down to <100 fs, using an integrated bulk compressor.

The Spirit-NOPA-VISIR is fully computer controlled to enable user-friendly operation. To cover 2P excitation imaging and applications in optogenetics as well, the Spirit-NOPA-VISIR can be configured with a dual pulse length option. With this option, narrow bandwidth, uncompressed laser pulses are available over an extended tuning range of the Spirit-NOPA-VISIR, closing the gap between signal and idler. The dual pulse length option is ideally suited for photostimulation of neurons in optogenetics and excitation of fluorescent dyes in the 900 nm to 1200 nm spectral range.

Spirit NOPA Built-In Harmonic Generator

Spirit-NOPA-3H includes a built-in third harmonic generator and its output is tunable from 520 nm to 900 nm with a pulse width as short as sub-30 fs and an output energy up to >0.5 μJ.

Spirit-NOPA-2H includes a built-in second harmonic generator, to convert the Spirit IR beam to 520 nm. The output of the Spirit-NOPA-2H is tunable from 650 nm to 900 nm with a pulse width as short as sub-30 fs and an output energy up to >3 μJ.

Spirit-NOPA (-3H, -2H) is fully computer controlled to allow for easy wavelength tunability. Its built-in bandwidth selector and integrated computer controlled compressor provide a pulse width agility unmatched by other ultrafast laser technologies.
