Schematic of the experimental setup. (WP–wave plate; C–cube polarizer; M–mirror; W–Wollaston prism; L–lens; F–filter; BD–beam dump).
The in-band CE as a function of the lens-target distance for f/10 and f/5 lenses is given. A 25 ns laser pulse is used.
The pulse width effect on the in-band CE of CO2 laser-produced Sn plasma by keeping the lens at the best focal position and the optimal CE value lens position. The power density used at the best focal position was .
The Sn UTA spectra recorded with different lens positions with respect to the target surface is given. The spectra are time-integrated and a f/10 meniscus lens is used for focusing the laser.
The density profiles recorded 5 ns after the peak of the laser pulse using a Nomarksi interferometer. The density profile is obtained with (a) the best lens focal position and (b) the best CE lens position. A f/10 meniscus lens is used for focusing laser.
