Abstract.

The spatially integrated emission of harmonics from two along the propagation axis spatially separated sources has been investigated as a function of the relative phase and relative emission power of the two sources. Temporal interference fringes have been observed with frequency distributions including multiples of the driving Ti:sapphire laser frequency. The interference fringes provide evidence of harmonic emission that is sensitive to the relative emission phases and intensities of the two sources. Thus they demonstrate control of the emission at the following source by the harmonics emitted at the preceding one. The observed interference frequencies are discussed qualitatively and some of them are attributed to resonant processes.
