Abstract:
Saturated tabletop lasers having increased output energy and operating at 5 Hz repetition rate, were demonstrated at wavelengths about 18. 9 nm for molybdenum targets, 16. 4 nm for ruthenium targets, 14. 7 nm for palladium targets, 13. 9 nm for silver targets, and 13. 2 nm for cadmium targets in transitions of nickel-like ions. The results were obtained using a sequence of two, plasma-generating pre-pulses, each having sub-Joule energy followed after a selected delay period by picosecond laser plasma excitation pulses having with an energy of about 1 J at angles of incidence optimized for maximum energy deposition.
