Abstract

Potential applications of ultrashort vortex pulses (ultrashort pulses with helical wavefronts) require compact tools to compensate for dispersion during their generation and propagation. In this work, a global simulated-annealing optimization algorithm, based on analysis of the temporal properties and waveforms of femtosecond vortex pulses, is used to design and optimize chirped mirrors. Performances of the algorithm through different optimization approaches and chirped mirror designs are presented.
