摘要

The coherence properties of a 46.9-nm soft-x-ray laser beam produced in a capillary discharge plasma have been investigated. The beam is produced in a regime that is free from the effect of refraction defocusing, with a divergence of only 0.5-0.6 mrad. The discharge plasma is produced in capillary channels with length of 45 cm, where the Fresnel number of the gain medium is of the order of unity. The full laser energy is about 300 muJ. The spatial coherence of the laser has been experimentally investigated using a Young's double-slit interferometer and analyzed assuming a Gaussian Schell-model source and the generalized Van Cittert-Zernike theorem. We demonstrate the achievement of almost full spatial coherence and a near-Gaussian intensity distribution.
