Abstract

We theoretically study the photoelectron momentum spectra of the negative hydrogen ions by few-cycle orthogonally polarized two-color (OTC) laser pulses. It is found that the photoelectron momentum spectra can be effectively manipulated in the polarized plane by few-cycle OTC laser pulses. The results qualitatively agree well with the prediction of the simple man’s model. Finally, the effects of the duration of laser pulse on the photoelectron momentum spectra are discussed. The present work is meaningful for the optical control of the laser induced photodetachment of negative ions.
