Optical amplifier Spirit-NOPA®

measuringultra-rapidparametric

The Spirit-NOPA is a family of automated non-collinear optical parametric amplifiers (NOPA) specifically built and optimized for the industry-proven Spirit® HE and Spirit® One™ ultrafast lasers. The turn-key, high repetition rate Spirit femtosecond laser combines with the Spirit-NOPA to create a powerful, user-friendly tunable, high repetition rate source of ultrashort pulses for in-vivo, deep tissue imaging in neuroscience, spectroscopy, and other ultrafast scientific applications. High pulse energy for 3-photon imaging Broad tuning range: 650 nm to 900 nm (signal), 1200 nm to 2500 nm (idler) Optional pulse compression: <70 fs (signal), <100 fs (idler) High repetition rate, ultrashort pulses Wavelength range from UV to near-IR Integrated pulse compressor Features 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.
