Large aperture single crystal silicon turning flat mirrors provide a new method of high energy laser beam sampling for optical performance diagnostic measurements. This new sampling technique has been successfully implemented on the Alpha Laser Optimization program where transmitted beams through two, uncooled silicon mirrors have been used to measure total energy, instantaneous power, spectral content, and beam jitter. The accuracy of these measurements has been confirmed by independent measurements of these same parameters, and the results fall within expected error bars.
