Characteristics and Applications of Spatiotemporally Focused Femtosecond Laser Pulses

open access: yesApplied Sciences, 2016
Simultaneous spatial and temporal focusing (SSTF) of femtosecond laser pulses gives rise to strong suppression of nonlinear self-focusing during the propagation of the femtosecond laser beam.
