We demonstrate a fiber-based, three-color femtosecond source for simultaneous imaging of
three fluorescent proteins (FPs) using two-photon fluorescence microscopy (2PM). The three …

We present a new multimode dispersion measurement technique based on the time-of-flight
method. The modal delay and group velocity dispersion of all excited modes in a few-mode …

Astrocytes play a key role in the central nervous system. However, methods of visualizing
astrocytes in the deep brain in vivo have been lacking. 3‐photon fluorescence imaging of …

We report on a watt range laser system generating picosecond pulses using electro-optical
