Description
The attosecond lighthouse effect is a method to spatially separate attosecond XUV
pulses generated by surface harmonics. For the lighthouse effect, the incident laser pulse has an angular chirp and exhibits spatio-temporal couplings, namely wave-front rotation, in focus. Rotating wavefronts lead to the emission of attosecond pulses under an angle an thus to separate pulses far away from the target. The angular emission pattern is also affected by surface dynamics (’denting’) and we performed two dimensional PIC simulations with the EPOCH PIC code of this effect to study the influence of laser pressure induced surface denting on the attosecond pulse generation.
