However,for long (nanosecond) pulses and easily removable material (like PMMA)this changes from 0% at the beam periphery up to ~90% at the ablation contour and, therefore,the profile of imprinted pattern can be relatively deep(up to 200-300 nm by one shot).A suggested interpretation explains this fact in terms of gradual release of target material during laser pulse, which is accompanied by gradually increased laser penetration depth.However, simultaneously laser attenuation in ablated plum should be considered.The detail dynamics of this process is Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2016
