Spirit-NOPA® Broadly Tunable Optical Parametric Amplifiers for 3-Photon Imaging in Neuroscience and Other Ultrafast Scientific Applications 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. Spirit-NOPA-VISIR delivering unprecedented performance 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. Spirit-NOPA Advantage Spirit-NOPA-VISIR: • 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) • Dual pulse length option to bridge the gap in the tuning range Spirit-NOPA (-2H and -3H): • High repetition rate, ultrashort pulses • Wavelength range from UV to near-IR • Integrated pulse compressor • 3-photon excitation microscopy • Single molecules studies • Nanomaterials science • Ultrafast surface dynamics • Mult

Typical Spirit-NOPA-VISIR Performance1 (Pump by a Spirit HE 1040-30 at 30 W and 1 MHz, Compressed Output) 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...
