P., et al., Attosecond Time-Scale Intra-atomic Phase Matching of High Harmonic Generation, Physical Review Letters 86, no. 24 (11 June 2001): 5458-5461.http://hdl.handle.net/10217/68042Using a model of high-harmonic generation that couples a fully quantum calculation with a semi-classical electron trajectory picture, we show that a new type of phase matching is possible when an atom is driven by an optimal optical waveform. For an optimized laser pulse shape, strong constructive interference is obtained in the frequency domain between emissions from different electron trajectories, thereby selectively enhancing a particular harmonic order. This work demonstrates that coherent control in the strong-field regime is possible by adjusting the peaks of a laser field on an attosecond time scale.born digitalarticleseng©2004 American Physical Society.Copyright and other restrictions may apply.
