ABSTRACT:
A device for producing extended plasmas for x-ray lasers. In an evacuated using, a pair of tungsten blocks are placed just above a target surface and spaced apart to form a channel. A high power laser beam is focused to a point on the target creating a plasma between the blocks. As the plasma expands away from the target in the z-direction, the tungsten blocks confine the plasma in the y-direction and plasma species of higher stages of ionization are formed into a jet of rectangular x-y cross section in the z-direction by the blocks. The plasma remains confined in the y-dimension or is focused in this direction above the blocks where sufficient amplification occurs to provide x-ray lasing along the x-axis.
