1. A laser beam generation system, comprising:
a first laser chip configured to generate a first polarized laser beam;
a second laser chip configured to generate a second polarized laser beam;
a polarizer configured to combine the first polarized laser beam and the second polarized laser beam to generate a third laser beam; and
a printed circuit board (PCB),
wherein the PCB is formed in an L-shape with a first portion extending in a first direction and a second portion extending in a second direction perpendicular to the first direction,
wherein the first laser chip is disposed on the first portion such that the first polarized laser beam is emitted in a direction parallel to the second direction,
wherein the second laser chip is disposed on the second portion such that the second polarized laser beam is emitted in a direction parallel to the first direction, and
wherein the first and second laser chips are configured to generate the first and second polarized laser beams, respectively, at different time slots.
