ABSTRACT:
Generation of 2 μW average output power at 13.9 nm from a table-top laser-pumped Ni-like Ag laser operating at 5 Hz repetition rate using a silver-coated helical target which is rotated and advanced such that the target surface is renewed between pulses, is described. Greater than 2×104soft x-ray laser pulses were obtained using a single target. Similar results were obtained at 13.2 nm for Ni-like Cd using a cadmium-coated target. Uninterrupted operation of laser-pumped soft x-ray lasers at a repetition rates of about 10 Hz for periods of several hours enables the generation of pulsed, high average power soft x-rays for applications. Other embodiments of the renewable laser target are described.
