We demonstrate non-invasive, high-resolution, in vivo imaging of subcortical structures (the external capsule (EC) and hippocampus) within an intact mouse brain using three-photon fluorescence… (More)
We compare the maximal two-photon fluorescence microscopy (TPM) imaging depth achieved with 775-nm excitation to that achieved with 1280-nm excitation through in vivo and ex vivo TPM of… (More)
Deep tissue in vivo two-photon fluorescence imaging of cortical vasculature in a mouse brain using 1280-nm excitation is presented. A record imaging depth of 1.6 mm in mouse cortex is achieved in… (More)
We present a compact and flexible endoscope (3-mm outer diameter, 4-cm rigid length) that utilizes a miniaturized resonant/nonresonant fiber raster scanner and a multielement gradient-index lens… (More)
Multiphoton microscopy (MPM) is widely used for optical sectioning deep in scattering tissue, in vivo [1-2]. Phosphorescence lifetime imaging microscopy (PLIM)  is a powerful technique for… (More)
We present a technique for tunable dispersion compensation that is low cost, high speed, and has a large tuning range. By rotating a cylindrical lens at the Fourier plane of a folded 4f grating pair… (More)
Deep tissue multiphoton imaging of mouse brain using 1280-nm excitation is presented. A record imaging depth of 1.5-mm in mouse cortex is achieved in vivo, approximately reaching the fundamental… (More)
We demonstrate high-energy soliton pulse generation from a large mode area fiber, tunable from 1560 nm up to 1700 nm, pumped with a 10 MHz, 1.5-ps time lens source at 1544 nm.
We demonstrate 67-nJ, 65-fs soliton pulse generation using a solid-core photonic crystal rod pumped by a compact fiber source, and its application to in vivo three-photon microscopy in mouse brain.
