摘要
The generation of coherent extreme ultraviolet radiation by phase-matched high-order difference frequency mixing in plasmas is reported. The plasmas are produced by optical field ionization of atomic and molecular gases in an intense Ti:sapphire laser field. Phase matching for the high-order two-color (omega,2 omega) mixing process, 9 omega = 6(2 omega) - 3 omega, is demonstrated for the first time.
