1. A laser soldering system, applying for processing a first element and a second element with different processing temperatures, wherein the first element is adjacent to the second element, and the laser soldering system comprises:
a laser source module configured to emit a laser beam;
a polarization adjusting assembly, comprising:
a plurality of polarization elements configured to split the laser beam into a Gaussian beam and a ring-shaped beam, wherein the Gaussian beam illuminates the first element, and the ring-shaped beam is illuminates the second element; and
at least one stepping motor configured to adjust a size of the ring-shaped beam;
a temperature sensor configured to monitor a temperatures of the first element and a temperature of the second element; and
a controller electrically connected to the temperature sensor, the laser source module, and the polarization adjusting assembly.
