Rogers, Edward T.F., Stebbings, Sarah L., de Paula, Ana M., Froud, Christopher A., Praeger, Matthew, Mills, Benjamin, Grant-Jacob, James, Brocklesby, William S. and Frey, Jeremy G. (2012) Spatiotemporal phase-matching in capillary high-harmonic generation Journal of the Optical Society of America B, 29, (4), pp. 806-812. (doi:10.1364/JOSAB.29.000806).

Record type: Article


We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce the spectral envelope of experimentally generated harmonics. The model demonstrates that an ionization-induced phase mismatch is limiting the energy of the generated harmonics in current capillary high-harmonic generation experiments. The success of this model shows that phase-matching processes play a dominant role in determining the emission from capillary high-harmonic generation.
