  Photoelectron angular distributions (PADs) of oriented polar molecules in
response to different polarized lasers are systematically investigated. It is
found that the PADs of polar CO molecules show three distinct styles excited by
linearly, elliptically and circularly polarized lasers respectively. In the
case of elliptical polarization, a deep suppression is observed along the major
axis and the distribution concentrates approximately along the minor axis.
Additionally, it is also found that the concentrated distributions rotate
clockwise as the ellipticity increases. Our investigation presents a method to
manipulate the motion and angular distribution of photoelectrons by varying the
polarization of the exciting pulses, and also implies the possibility to
control the processes in laser-molecule interactions in future work.
