Self-Organized Pattern Formation with Ultrafast White-Light

Abstract

A broad-band white-light (WL) spectrum (filtered, roughly ranging from ≈ 400nm≤ λ$\approx 400\text{nm}\le {{\lambda }_{wl}}\le 800\text{nm}$ ≤ 800nm), with significantly reduced spatial coherence, can only be obtained at the highest available input pump energy. For this reason, it was chosen to irradiate the samples, in the corresponding set of experiments, with a constant WL pulse energy and vary the irradiation dose (I _D = f(N · F)), through the number of applied pulses N.
