Investigation on Laser-driven RT Instability Using Soft X-ray Laser
Abstract
The experiment of laser-driven Rayleigh-Taylor (RT) instability on Shenguang II (SG-II) facility has been presented. A Ni-like silver soft x-ray laser at 13.9nm has been used as a probe to take radiography of the modulation target RT instability first time. The modulation target is irradiated by a laser beam at 527nm of wavelength, 1500J of energy and 2.4ns of pulse width (FWHM), which is focused to intensity of 4×1014Wcm-2 on the target by a lens array. The evolvement of RT instability has been observed clearly. The results obtained by numerical simulation agree with that given by experiments.
