Abstract
The effects of random polarization of a laser beam is reduced by separating the polarized laser beam into first and second polarized components that are orthogonal to each other, and measuring the energy in each of the first and second components. The total energy in both of the first and second components are compared with a predetermined energy level. The energy output of the laser beam is controlled in response to the measured comparison.
