Light into the dark of the brain functions

Within the life sciences, deriving neuronal activity in deep brain regions is an important process. In neuroscientific experiments, nerve cells are labeled with fluorescent proteins, which are optically excited by laser pulses that have the ability to transmit neuronal activity by fluorescence differences.

Researchers from the Gene Circuit Behavior Department of the Max Planck Institute of Neurobiology and Menlo Systems developers have teamed up to apply the latest technologies in the field of fiber-based laser technologies for neuronal circuit research.

For the first time, the YLMO-930, a revolutionary new Menlo Systems  femtosecond fiber laser, was used in this cooperation. The YLMO series was developed for OEM integration with 24/7 operation. With an average output power of >1 W around 930 nm, the YLMO-930 is optimized for the 2-photon fluorescence excitation of green fluorescent protein GFP and its variants. In combination with the very compact footprint, the YLM0-930 is the perfect choice for life sciences applications where reliability counts.
