Brighten Up Your Images in Multiphoton Microscopy??

Brighten Up Your Images in Multiphoton Microscopy??

To improve the contrast and brightness of your nonlinear fluorescence images, TOPTICA’s FemtoFiber ultra 920 incorporates Clean Pulse Technology - a laser design that significantly reduces pedestals and side-wings on the temporal pulse profile compared to other laser amplifier designs.?

For the excitation laser in 2-photon microscopy, a combination of high temporal pulse quality (a “clean pulse”) and a short pulse duration at the sample plane improves the contrast and brightness of fluorescence images.?

In order to achieve the best image quality, TOPTICA’s FemtoFiber ultra is equipped with Clean-Pulse Technology that reduces pedestals and side-wings on the temporal pulse profile. Hence, the full laser power contributes to two-photon excitation. Clean-Pulse Technology provides highest fluorescence image brightness and contrast while keeping thermal heating of the sample to a minimum.

Additionally, TOPTICA’s FemtoFiber ultra provides motorized group delay dispersion (GDD) pre-compensation that can be controlled in software.

Amazing! I'd never have thought that there is still so much efficiency to be gained.
