Laser Beam Pointing Stabilization

Laser interferometer gravitational wave observatory was comprehen sively characterized.

Laser beam pointing stabilization. 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. Encyclopedia letter b beam pointing fluctuations. Laser beam p ointing and stabilization by intensity f eedback contr ol n estor o. Call this x and y.

The linear component comes from the horizontal and vertical motion of the laser perpendicular to the axis of propagation. Laser power frequency beam pointing and beam quality were simultaneously stabilized using different active and passive schemes. Aligna automated laser beam alignment and stabilization system the aligna system is a complete solution for beam pointing stabilization. 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. This includes spectral beam combining adaptive optics precision pointing line of sight stabilization and air flow control. P erez arancibia james s. Laser beam pointing stabilization system laser optics labview automation imaging fluctuations of the laser pointing is a common problem in laser experiments.

Pointing and profile information while dedicated software implements a user friendly intelligent control algorithm that keeps the beam s four degrees of freedom precisely. With the powerful rp resonator software one can calculate how misalignments of mirrors cause beam pointing deviations. 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. They cause a temporal variation of the laser energy as well as reducing the coupling efficiency between the amplifier states.

The output beam the performance of the stabilization and the. The laser shutter system beamblock is designed for the combination with the beam stabilization system but can also be used independently. 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. Because high power laser system always operates at a low repetition it is effective too ensure the beam pointing stability by a passive technique such as using a stable mechanical.

Beam pointing fluctuations analyzing beam positing fluctuations. 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. Ask rp photonics for advice on the origin of beam pointing fluctuations and their reduction with suitable laser designs or with feedback stabilization.
