Simulation of self-focusing of laser beams in condensed media

Simulation of lasing networks with quantum graphs and SALT theory.

Simulation of filamentation of laser beams in condensed media

Fluorescence correlation spectroscopy (FCS) is a technique that detects diffusion of fluorescent species through a small focal volume. From FCS measurements, quantitative data such as particle size, binding constants for interactions of biological molecules, and local viscosity can be probed.

Interactive PyQt5 application for designing and evaluating paraxial Gaussian laser beamlines.

CRIME-based algorithms for laser-electric waveform reconstruction
