Multiphoton Polarization Ratio as a Sensitive Indicator of Specific Intensity Effects

Conference paper


Direct observation of specific field-intensity effects in elementary processes has proven to be elusive. For example, in multiphoton ionization of low pressure noble gases, it has been found1 that the total transition probability retains its In° dependence up to very high intensity I, where no is the lowest multiphoton order in which ionization can occur. It had been expected that a logarithmic plot of transition probability W versus intensity would show a departure from the straight line behavior d (log W)/d (log I) = no at high intensity.
