Laser Beam Pointing Stabilization

Pointing and profile information while dedicated software implements a user friendly intelligent control algorithm that keeps the beam s four degrees of freedom precisely.

Laser beam pointing stabilization.

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. Beam pointing fluctuations analyzing beam positing fluctuations. 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.

This locks the beam pointing to sub micrometer precisions. The laser shutter system beamblock is designed for the combination with the beam stabilization system but can also be used independently. 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. They cause a temporal variation of the laser energy as well as reducing the coupling efficiency between the amplifier states.

The linear component comes from the horizontal and vertical motion of the laser perpendicular to the axis of propagation. With the powerful rp resonator software one can calculate how misalignments of mirrors cause beam pointing deviations. 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. Laser interferometer gravitational wave observatory was comprehen sively characterized.

Ask rp photonics for advice on the origin of beam pointing fluctuations and their reduction with suitable laser designs or with feedback 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 includes spectral beam combining adaptive optics precision pointing line of sight stabilization and air flow control. The output beam the performance of the stabilization and the.

Laser power frequency beam pointing and beam quality were simultaneously stabilized using different active and passive schemes. Call this x and y.
