>10 MW peak power, long wavelength enable deepest imaging of live tissue for neuroscience

Santa Clara, CA – February 11, 2016 – Spectra-Physics® introduces Spirit-NOPA-IR, a high peak power, tunable long infrared wavelength ultrafast source for 3-photon imaging. Pumped with the Spirit® industrial femtosecond laser, the new source generates an incredible >10 MW peak power and ultrashort <80 fs pulses with tunable wavelengths from 1200 to 1600 nm. Imaging with this new source results in exceptional clarity in live tissue at depths of up to >1 mm, ideal for neuroscience, embryology, and other bio-imaging research.

“The combination of the proven Spirit femtosecond laser with the new Spirit-NOPA-IR is a powerful solution for live, deep tissue imaging. In the critical field of brain imaging, the solution enables in vivo imaging of key subcortical structures in mice,” says Julien Klein, manager, product marketing at Spectra-Physics. “This new solution further expands our industry-leading portfolio of ultrafast lasers for bio-imaging.”

Long infrared wavelengths and utilization of the 3-photon excitation effect significantly reduce optical scattering in tissue, thereby allowing deeper imaging. Spirit-NOPA-IR pumped with the Spirit laser delivers the high peak powers necessary for 3-photon generation at long infrared wavelengths of 1200-1600 nm, while operating at moderate average powers to avoid damage to the live tissue. Spirit-NOPA-IR and Spirit are fully automated and computer controlled for flexible, easy-to-use operation. An optional SHG (second harmonic generation) output is available for 600 to 800 nm wavelengths.

Spectra-Physics’ Spirit and Spirit-NOPA-IR will be featured at SPIE Photonics West and BiOS, Moscone Center, San Francisco, California, February 13-14 and 16-18, 2016. Please visit Spectra-Physics at BiOS booth #8823 and Photonics West booth #1400 for a demonstration. For more information, please see
