The time resolved propagation of femtosecond and picosecond laser pulses within turbid
tissues is simulated by a Monte Carlo model. The internal distribution of irradiance for an …

In this study we investigated the light distribution under femtosecond laser illumination and
its correlation with the collected diffuse scattering at the surface of ex-vivo rat skin and liver …

The intensity of the early-arriving snake portion of 100-fs ultrashort laser pulses transmitted
through biological tissue of increasing thickness was measured by a streak camera. The …

The transmission of 100-fs ultrafast laser pulses through biological tissues was measured by
using femtosecond and picosecond time-resolved detection techniques. The broadening of …

Ultrashort laser pulses are finding increasing applications in biology and medicine. Such
pulses can be used directly or after non-linear modification. Direct utilization includes …

A dosimetric system has been developed to measure the spatially resolved light dose
absorbed by a photosensitizer in a tissue-simulating medium. These gelatin-based …

Monte Carlo simulations of photon propagation offer a flexible yet rigorous approach toward
photon transport in turbid tissues. This method simulates the “random walk” of photons in a …

Mechanisms of interaction between laser radiation and biological tissue are reviewed.
Scattering and absorption determine the penetration of radiation into tissue; the …

A three-dimensional Monte Carlo simulation of transient radiative transfer is performed for
short pulse laser transport in scattering and absorbing media. Experimental results of a 60 …

Transparent materials do not ordinarily absorb visible or near-infrared light. However, the
intensity of a tightly focused femtosecond laser pulse is great enough that nonlinear …
