Near‐Field Spatial Imaging and Time‐Resolved Measurements of the Ni‐like Palladium Soft X‐Ray Laser

We have performed a series of near‐field imaging experiments for the nickel‐like 14.7‐nm Pd x‐ray laser with the aim to characterize the two‐dimensional source intensity distribution and its position relative to the target surface. The effect of different prepulse amplitudes at variable main pulse‐to‐prepulse delays is investigated. To further characterize the nickel‐like 14.7‐nm Pd x‐ray laser, we then performed measurements of its pulse duration with the help of a streak camera.
