Abstract

With recent advances in miniature high performance tip and tilt mirror components (see details in another paper presented in this seminar), it is feasible to dynamically compensate for angular misalignment of intracavity optical components. The control system described in this paper seeks to maximize output power. The 2-axis active mirror mount is operated in a spiral scan mode searching for the optimum alignment in 2 dimensions. Data (frame) updating rates of 20 frames per second have been achieved by using a small 2" diameter beryllium mirror driven by a pair of "shaker motors." Extensions of this and similar approaches to different practical applications will be discussed together with preliminary experimental results.
