Abstract The three-dimensional electron–electron correlation in an elliptically polarized laser field is investigated based on a semiclassical model. Asymmetry parameter $\alpha$ of the correlated electron momentum distribution is used to quantitatively describe the electron–electron correlation. The dependence of $\alpha$ on ellipticity $\varepsilon$ is totally different in three directions. For the $z$ direction (major polarization direction), $\alpha$ first increases and reaches a maximum at $\varepsilon=0.275$, then it decreases quickly. For the $y$ direction in which the laser field is always absent, the ellipticity has a minor effect, and the asymmetry parameter fluctuates around $\alpha=-0.15$. However, for the $x$ direction (minor polarization direction), $\alpha$ increases monotonously with ellipticity though starts from the same value as in the $y$ direction when $\varepsilon=0$. The behavior of $\alpha$ in the $x$ direction actually indicates a transformation from the Coulomb interaction dominated correlation to the laser field dominated correlation. Therefore, our work provides an efficient way to control the three-dimensional electron–electron correlation via an elliptically polarized intense laser field.
