TY - JOUR AU - Stránský, M. AU - Rohlena, Karel TI - Optical spectra of FLASH generated plasmas JO - Physica scripta VL - T161 SN - 1402-4896 CY - Bristol PB - IoP Publ. M1 - DESY-2014-03780 SP - 014028 PY - 2014 AB - Time integrated measurements of optical spectra of the plasma generated by pulses of the free electron laser facility FLASH on a solid target at DESY Hamburg are interpreted in terms of plasma hydrodynamics. It is shown that the main contribution to the optical range comes from the expanding stage of the plasma evolution on a ns scale, whereas the UV part is partially obscured by the optically dense outstreaming plasma near the ablated hole LB - PUB:(DE-HGF)16 UR - <Go to ISI:>//WOS:000339620200029 DO - DOI:10.1088/0031-8949/2014/T161/014028 UR - https://bib-pubdb1.desy.de/record/172529 ER -
