Ultrash.las. pulses are usually described in terms of temporal and spatial dependences of their electric field,assuming that the spatial dependence is separable from time dependence.In most situations this assumption is incorrect as generation of ultrashort pulses and their manipulation lead to couplings between spatial and temporal coordinates resulting in various effects such as pulse front tilt and spatial chirp. One of the most intriguing spatiotemporal coupling effects is the so-called „lighthouse effect”, the phase front rotation with the beam propagation distance.
