Evidence of X-Ray Laser Gain Cancellation Due to Plasma Inhomogeneity,
Abstract
Influence of Random Phase Plates on homogeneity of long plasma columns is studied by X-ray imaging. Consequence on laser gain at 105.7 A is discussed. Compared to the collisional pumping scheme, the recombination scheme in lithium-like ions is an attractive way to carry out a small-scale X-ray laser because it is known to be potentially the cheapest way of soft X-ray pumping. With the gain values actually reported, a long plasma column, of about 5 cm, would make soft X-ray lasers using lithium-like ions already available in laboratories. However some difficulties are associated with large gain production in long plasma columns (L > or = 2 cm). The observation of a rather low gain coefficient (0.5/cm) seems to be the general fact for plasmas of such length.
