摘要
Interaction of TiSa femtosecond laser filament with solid target positioned in air during micromachining is accompanied by x-ray bursts. X-ray yield increase up to 4 times using chirped laser pulses (500fs) in compare to 60fs pulses with the same power. Hot electron temperature derived from x-ray spectra allowed to estimate peak intensity in filament, that appeared to he about 2001W/cm(2).
