Subsurface generation of hard X-rays by a BaF2 target exposed to repetitively pulsed radiation from a femtosecond Cr: forsterite laser at power densities below 10(15) W cm(-2)

摘要

The subsurface generation of hard X-rays (E gamma > 20 keV) is found during the formation of a channel by a train of 10(14) - 10(15)-W cm(-1) femtosecond laser pulses in a BaF2 target.
