PhD Seminar: Super Mode-Locking in Passively Mode-Locked Vertical External-Cavity Surface-Emitting Lasers
December 21, 2022 @ 8:00 am - 5:00 pm
Title: Super Mode-Locking in Passively Mode-Locked Vertical External–Cavity Surface–Emitting Lasers
Author: Denis Hessel
Abstract:
We analyze the dynamics of mode-locking in Vertical External-Cavity Surface-Emitting Lasers using a first-principles dynamical model based on delay algebraic equations. We show that apart from a conventional fundamental mode-locked state corresponding to one pulse per period, super mode-locked pulses exist. Using a combination of multi-scale analysis, path-continuation and direct numerical simulations, we disclose the mechanisms responsible for the emergence and stability of the super mode-locked state.
