description

The behaviour of a one-electron, one-dimensional, asymmetric molecule driven by a laser field of intermediate intensity is studied. At the laser intensity used, the electron bounces back and forth from one atom to another undergoing repeated collisions with the nuclei. The scattered electromagnetic spectrum shows even and odd harmonics of the pump frequency. By means of a wavelet transform it is seen that the harmonics are emitted at different instants of time, corresponding to different locations of the electron. It is suggested that the emission time can be used as a tool to determine the position of the electron.
