Description
In order to improve the contrast of a nanosecond prepulse, the interaction of 12 TW, 50 femtosecond laser pulses with thin foil, as a filter, is investigated. Due to the collisional absorption, the prepulse produces rapidly expanding plasma and can lose 90% of its energy. At a properly chosen thickness of the filter, more than 60% of energy of the femtosecond main pulse is shown to be transmitted through the expanded underdense plasma with reduced prepulse contrast ratio
