Quantification of spatial filamentation in large-area semiconductor lasers

Description

This research aims to identify an objective and precise quantifier of the degree of filamentation in the beam profile of wide area lasers (BAL) marketed by MONOCROM. BALs usually present complex spatial and temporal dynamics that generate moving bright spots (zigzag) across the beam width, a phenomenon that drastically reduces the optical quality and its suitability for applications that require homogeneous patterns. The project seeks to establish methods to perform quantitative comparisons between theoretical models and experimental data, identifying the optimal parameters that minimize the effect of filamentation.

Background

Oscar Ricardo holds a Master's degree in Physics from the Instituto Balseiro (Argentina), specializing in complex systems, where he completed a thesis on the dynamic analysis of genetic models. He has also been a research assistant at the University of Delaware (USA) performing molecular dynamics simulations. His basic training is as a physicist from the Universidad del Valle (Colombia), where he focused on the formation of domains in Ising chains under Glauber dynamics.

Motivation

His motivation comes from the intersection between his passion for complex systems and their application in practical physics. He is passionate about using statistical physics tools and his background in complex systems to characterize and understand the behavior of laser profiles in a real industrial environment like MONOCROM. His goal is to connect theory with technological innovation, contributing to improving laser design and strengthening the links between academia and industry.
