Improved High Energy Laser Beam Sampling Meter

摘要

This document discloses apparatus for accurately sampling and measuring beam power of a high energy laser beam without blocking or unduly perturbing the beam for phenomenological effects purposes and including a unitary sampling wheel which reflects a portion of the laser beam energy to a primary collecting and focusing mirror which re-reflects the laser beam onto a low level energy detector and a low level power detector for providing accurate and reliable samples through a wide range of frequencies and low amplitude without affecting beam characteristics and further use.
