  To add to the rapidly progressing field of ultrafast photocurrent, we propose
a universal method to generate photocurrent in normal and topological materials
using a pair of multicycle linearly polarized laser pulses. The interplay of
the fundamental and its second harmonic pulses is studied for the generation of
photocurrent in Weyl semimetals by varying the angle between the polarization
direction, relative intensity, and relative phase delay. It has been found that
the presence of a comparatively weaker second harmonic pulse is sufficient to
generate substantial photocurrent. Moreover, significant photocurrent is
generated even when polarization directions are orthogonal for certain ratios
of the lasers' intensities. In addition, the photocurrent is found to be
susceptible to the delay between the two pulses. We have illustrated that all
our findings are extendable to non-topological and two-dimensional materials,
such as graphene and molybdenum disulfide.
