摘要
An analytic expression for the transmission coefficient as a function of the foil thickness d describing penetration of intense femtosecond laser pulses through ultra-thin foils with a thickness of the order of 30-100 nm is derived using the Vlasov-Boltzmann equation. It is found that the transmission of laser radiation stops at the skin depth c/omega (p) , but sharp and narrow resonances occur for the foil thickness d > c/omega (p) with the transmission coefficient T = 1.
