Předneseno na:ICDMP Workshop and Expert Meeting,Warsaw, Poland, 10-11.10. 2014, On Dense Magnetised PlasmasAt interaction of long (i.e. nanosecond) pulses of XUV radiation with easily ablated solid surface the efficiency of removal of particles reaches even in the desorption region up to 90%. One of explanations might be a gradually increased penetration depth during duration of laser pulse. However, analytical description of this process is very complicated: removal of particles from the surface layer accompanies formation of cloud of these particles, the profile and dynamics, and therefore, even absorption of which is unknown. On the other hand, if a sample of difficult ablated material is used, then formation of cloud is minimised and the crater morphology can be used for fluence mapping.
