How capturing multiple colours simultaneously unlocks deeper biological insights
In advanced two-photon microscopy, capturing multiple colors simultaneously unlocks deeper biological insights. Metabolic imaging, in particular, gains from concurrent NADH and FAD signal acquisition. The FemtoFiber ultra dual-color setup from photonics specialist Toptica synchronises two FemtoFiber ultra lasers optically – eliminating the need for wavelength tuning.
The system's shared oscillator ensures precise all-optical synchronisation, delivering a fixed and stable time delay between the two laser wavelengths with minimal timing jitter. Plus, a single electronic trigger output provides a consistent timing reference for both FLIM (via TCSPC) and gated detection systems.
Toptica's fiber lasers for next-generation science and industry
Ultrafast laser technology has become a game changer across research and industry. Its unmatched combination of high peak power and ultrashort pulse duration enables strong nonlinear effects—paving the way for breakthroughs in scientific discovery and advanced engineering.
For successful deployment, though,robust, cost-effective systems with intuitive push-button operation is required.
Toptica’s FemtoFiber series delivers exactly that. Built on Erbium (Er) and Ytterbium (Yb) fiber platforms, models like the FemtoFiber smart, FemtoFiber ultra, and FemtoFiber dichro are engineered for performance and reliability.
These ultrafast lasers generate stable femtosecond and picosecond pulses using polarisation-maintaining fiber and SAM mode-locking.
With output options at 1560/780 nm, tunable VIS/NIR, IR/NIR supercontinuum, and short-pulse configurations, they support a broad range of applications – from nonlinear microscopy and two-photon polymerisation to THz time-domain systems, attoscience, and seeding high-power lasers.
