Show Abstract
Conversion efficiencies (CEs) from incident laser energy to 13.5 nm light within a 2% bandwidth were measured with changing laser pulse durations for laser-produced tin plasmas. Experimental results indicate that the optimum pulse duration is determined by two parameters: one is the optical depth of tin plasma for 13.5 nm light and the other is laser absorption rate in 13.5 nm emission-dominant region. The maximum CE of 2.2% is obtained with pulse duration of 2.3 ns.
