  Charge transport through a rectangular vector potential barrier modulated by
a continuum laser in monolayer phosphorene is studied theoretically in the
ballistic regime along the line of Floquet formalism. Laser free transmission
profile displays strong directional behavior exhibiting collimation depending
on the incident energy and width of the barrier. However, the application of
laser, polarized along the zig-zag direction, creates a sharp anti-resonance in
the transmission spectrum and reveals a strong light matter interaction due to
broken symmetry in presence of the magnetic vector potential. Transmission
properties through a vector barrier are found to be sensitive particularly for
lower frequency and higher intensity of the laser. For a thin barrier, the
laser assisted conductance is suppressed remarkably in contrast to its
oscillatory nature for a thicker one.
