Abstract
An optical module adjusts an output of a laser of a laser processing machine. The optical module consists essentially of includes an adaptive spherical mirror configured to receive a laser beam from the laser, and a spherical mirror configured to receive a laser beam reflected from the adaptive mirror. Both the adaptive mirror and the spherical mirror have a phase-shifting coating such that the laser beam reflected from the spherical mirror has a circular polarization.
