GFP excitation: Absorption spectra of GFP proteins plotted together with the output spectrum of the YLMO-930. The laser is ideally suited for 2-photon fluorescence imaging with GFP and its variants.



Our cognition and behavior are determined by single neurons and groups of neurons communicating with one another. Femtosecond lasers enable us to understand and even to interfere with those communication patterns on the microscopic level.
