  We theoretically investigate the effects of laser polarization on
photoelectron angular distribution through laser-induced continuum structure.
We focus on a polarization geometry where the probe and dressing lasers are
both linearly polarized, and change the relative polarization angle between
them. We find that the total ionization yield and the branching ratio into
different ionization channels change as a function of the relative polarization
angle, and accordingly the photoelectron angular distribution is altered. We
present specific results for the $4p_{1/2}$-$6p_{1/2}$ and
$4p_{3/2}$-$6p_{3/2}$ systems of the K atom, and show that the change of the
polarization angle leads to the significant modification of photoelectron
angular distribution.
