High Q Laser in Hohenems / Bregenz, Austria, has released a new femtosecond light source for multi-photon microscopy – the new model “femtoTRAIN IMAGING”, a compact, all-in-one, alldiode-pumped, Ti:Sapphire oscillator.

The “femtoTRAIN IMAGING” offers light pulses with a duration of 100 fs at an average power of 200 mW. Its pulse width is optimized for minimal broadening in multi-photon microscope systems. It is available at fixed center wavelengths of 790, 810, 850 or 870 nm, respectively, optimized for the most popular two-photon microscopy dyes.

The “femtoTRAIN IMAGING” incorporates, at a footprint of only 53 cm by 20 cm, fs-resonator and pump laser in one monolithic housing. The semiconductor saturable absorber mirror (SESAM) assures passive and self-starting mode locking, offering a robust and stable system.
It is the ideal femtosecond laser source for two-photon microscopy due to its compact size, its hands-free, true turnkey operation and its attractive price.

The “femtoTRAIN IMAGING ” is designed to excite, by two-photon-absorption, all fluorescent proteins (GFP, CFP and YFP) and other relevant dyes such as Alexa Fluor 633, DiA, Lucifer Yellow, Oregon Green and Sytox Green. A module for negative dispersion is optional available for compensating the dispersion in the optics path.
