The effect of pre-pulse on x-ray emission from nano-structured target irradiated by high power pulsed laser
In this paper, the enhanced continuum x-ray emission from nano-targets irradiated by long laser pulses is investigated numerically. The calculations are performed under different prepulse conditions, and the x-ray emissions from solid and nano-structured target are compared. The results show that x-...

Summary: | In this paper, the enhanced continuum x-ray emission from nano-targets irradiated by long laser pulses is investigated numerically. The calculations are performed under different prepulse conditions, and the x-ray emissions from solid and nano-structured target are compared. The results show that x-ray yield can be enhanced significantly using a nano-layer with appropriate density. In addition, x-ray enhancement can be improved using a laser pre-pulse with appropriate intensity and delay time. The results also show that the enhancement can be reduced for prepulse intensities greater than the specific value (i. e. 1013 W/cm2). The effects of delay time between the main pulse and prepulse are also investigated. |
