Abstract:  

During this talk, I will present our recent results on phase locking of lasers and on imaging by using a multi-mode laser cavity. Phase locking of lasers corresponds to the state where all the lasers have the same constant relative phase and frequency. I will present new coupling schemes for phase locking hundreds of lasers and show how phase locking can be used for solving minimization problems, investigating phase transitions and spin systems, imaging through scattering media, high-resolution beam shaping and more.

 

Biography:

Dr. Mahler is currently a Ph.D. student in optics at the Weizmann Institute of Science under the supervision of professors Nir Davidson and Asher A. Friesem.  He did his master in complex system at the University of Paris-Saclay. During his PhD, Simon focused on the analogy between an array of coupled lasers and phase transitions and studied various phenomena including nonlinear coupling, XY/Ising models, first-order transitions, topological defects, fast suppression of speckle and beam shaping. Simon is the recipient of The Ruth and Prof. Abraham (Edek) Blaugrund Prize for outstanding physics PhD students in Weizmann. Simon grew up in Marseille, in the south of France. He is a big fan and player of soccer, volleyball and belote.
