Simulation of self-focusing of laser beams in condensed media

Simulation of lasing networks with quantum graphs and SALT theory.

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.

Simulation of filamentation of laser beams in condensed media

Browser-based laser photonics simulation suite — Gaussian beam propagation, nonlinear crystal phase-matching, cavity eigenmode, OPO design. Built with Claude Code.

CRIME-based algorithms for laser-electric waveform reconstruction

Tool for processing the results of an experiment on measuring the frequency-angular and integrated frequency spectrum

A simulation of digital signal processing techniques for suppressing laser phase noise in fiber-optic sensing systems. The project compares raw signals, Wiener filtering, and reference delayed self-heterodyne (DSH) techniques to recover low-frequency vibration signals using affordable commercial lasers.
