Abstract Hydrogen peroxide (H 2 O 2) has been identified recently as a meaningful signaling
molecule. The ability to perform imaging of H 2 O 2 in complex biological organisms with a …

We demonstrate an accurate quantitative characterization of absolute two‐and three‐photon
absorption (2PA and 3PA) action cross sections of a genetically encodable fluorescent …

We present brain imaging experiments on rat cortical areas, demonstrating that, when
combined with a suitable high-brightness, cell-specific genetically encoded fluorescent …

We demonstrate label‐free imaging of genetically induced hepatocellular carcinoma (HCC)
in a murine model provided by two‐and three‐photon fluorescence microscopy of …

Graphene saturable absorbers (GSAs) have been widely applied in ultra-fast mode-locked
fiber lasers. Thanks to the broadband advantage of graphene, we theoretically and …

We demonstrate a multimodal nonlinear-optical imaging that combines second-and third-
harmonic generation (SHG and THG) with three-photon-excited fluorescence (3PEF) as a …

By precisely managing fiber-optic nonlinearity with anomalous dispersion, we have
demonstrated the control of generating plural few-optical-cycle pulses based on a 24-MHz …

We demonstrate stain-free, high-contrast, subcellular-resolution imaging of astroglial cells
using epi-detected third-harmonic generation (THG). The astrocyte-imaging capability of …

We have demonstrated 30-Hz three-photon imaging using a single 24-MHz mode-locked Cr:
forsterite oscillator with a center wavelength at 1260 nm. By managing the dispersion …

At the level of peak powers needed for a Kerr-lens mode-locked operation of solid-state
soliton short-pulse lasers, a periodic perturbation induced by spatially localized pulse …
