Characterization of a 10 Hz double-pulse non-normal incidence pumped transient collisional Ni-like molybdenum soft x-ray laser for applications

摘要

Stable and reliable operation of a nickel-like molybdenum transient collisional soft x-ray laser at 18.9 nm demonstrated and studied with a 10 Hz Ti:sapphire laser system proves the suitability of the double-pulse nonnormal incidence pumping geometry for table-top high repetition soft x-ray lasers and broadens the attractiveness of x-ray lasers as sources of coherent radiation for various applications. X-ray laser emission with pulse energies well above 1μJ is obtained for several hours at 10 Hz repetition-rate without realignment under optimized double pumping pulse parameters including energy ratio, time delay, pulse duration and line focus width.
