Notes:
We have designed a new focusing system with a five-segmented prism array in combination with a beam expander and cylindrical lens assembly for compact x-ray laser experiments using a yttrium–aluminum–garnet (YAG) laser. The focusing characteristics were examined from irradiation patterns on a target. It was found that a beam of 25 mm diameter whose intensity profile was not uniform was condensed to a focused line having about 12 mm length and 50 μm width with a flat intensity distribution along the line on average, though the small-scale intensity modulation due to interference among the beamlets was observed. Spectroscopic observation of the plasma produced by irradiating the YAG laser of 2 J energy onto an Al slab target showed that highly ionized ions were produced up to the Li-like ionic stage. The new lens system is useful for compact x-ray laser research. © 1999 American Institute of Physics.
