P erez arancibia james s. It is hard to use conventional active beam pointing stabilization techniques based on closed loop feedback for a single shot or low repetition rate laser system. Lockheed martin breakthroughs are boosting the performance of laser weapon systems for ground air and sea platforms while shrinking their size weight and power consumption. Pointing and profile information while dedicated software implements a user friendly intelligent control algorithm that keeps the beam s four degrees of freedom precisely.

This includes spectral beam combining adaptive optics precision pointing line of sight stabilization and air flow control. With the powerful rp resonator software one can calculate how misalignments of mirrors cause beam pointing deviations. Laser interferometer gravitational wave observatory was comprehen sively characterized. Designed for accuracy reliability and ease of use the guidestar ii system is the answer to laser beam drift correction for the most demanding laser applications.

Gibson and tsu chin tsao abstract this paper pr esents an investigation of the contr ol pr oblem of aiming a laser beam under dynamic disturbances using light intensity for feedback. There are actually two components to laser pointing and laser pointing stability linear and angular which combine to affect the beam s position. This locks the beam pointing to sub micrometer precisions. The beam is steer ed with.

Aligna automated laser beam alignment and stabilization system the aligna system is a complete solution for beam pointing stabilization. They cause a temporal variation of the laser energy as well as reducing the coupling efficiency between the amplifier states. Ask rp photonics for advice on the origin of beam pointing fluctuations and their reduction with suitable laser designs or with feedback stabilization. Beam pointing fluctuations analyzing beam positing fluctuations.

The output beam the performance of the stabilization and the. Together the control electronics a combined angle and position detector and two active mirrors form a feedback loop which suppresses thermal drifts as well as fast fluctuations. The laser shutter system beamblock is designed for the combination with the beam stabilization system but can also be used independently. Encyclopedia letter b beam pointing fluctuations.

The linear component comes from the horizontal and vertical motion of the laser perpendicular to the axis of propagation. Call this x and y. Laser beam pointing stabilization system laser optics labview automation imaging fluctuations of the laser pointing is a common problem in laser experiments.
