Intensity-resolved above-threshold ionization of xenon with short laser pulses
We present intensity-resolved above-threshold ionization (ATI) spectra of xenon using an intensity scanning and deconvolution technique. Experimental data were obtained with laser pulses of 58 fs and a central wavelength of 800 nm from a chirped-pulse amplifier. Applying a deconvolution algorithm, we obtained spectra that have higher contrast and are in excellent agreement with characteristic t...

متن کاملCarrier-envelope phase dependence of nonsequential double ionization of H2 by few-cycle laser pulses
We studied the dependence of double ionization of H2 molecules on the carrierenvelope phase of a few-cycle laser pulse in the nonsequential double ionization regime. For short pulses at low intensities the strong dependence is due to the return energy of the rescattering electrons and the result may be used for determining the absolute value of the carrier envelope phase.
متن کاملEnhancing high-order above-threshold dissociation of H2+ beams with few-cycle laser pulses.
High-order (three-photon or more) above-threshold dissociation (ATD) of H(2)(+) has generally not been observed using 800 nm light. We demonstrate a strong enhancement of its probability using intense 7 fs laser pulses interacting with beams of H(2)(+), HD(+), and D(2)(+) ions. The mechanism invokes a dynamic control of the dissociation pathway. These measurements are supported by theory that a...
