Abstract

Summary form only given. Liquid crystal modulators (LCMs) are the most widely used modulators in femtosecond pulse shapers. The pixellated nature of an LCM is known to give rise to low intensity replica pulses (Weiner et al, IEEE J. Quantum Electron., vol. 28, p. 908, 1992). Our study shows that a subtle nonlinear spatial dispersion has a profound effect on the characteristics of the replica pulses and may dramatically reduce their (already low) peak intensity.
