Pis'ma Zh. Eksp. Teor. Fiz. 60, No. 4, 235-239 (25 August 1994) A. mechanism for the resonant generation of high harmonics of a laser beam is discussed. This method may make it possible to increase the conversion coefficient substantially and to move to shorter wavelengths. In particular, it is sstimated that harmonics in the region λ = 100 A can be generated with in efficiency on the order of 10^5 in a beryllium plasma. © 1994 American
