Laser Beam Stabilization System

The basic configuration of the compactsystem is fully equipped for stabilization tasks in laser machines.

Laser beam stabilization system.

Andreas velten created date. Aligna automated laser beam alignment and stabilization systemthe aligna system is a complete solution for beam pointing stabilization. The laser shutter system beamblockis designed for blocking high power laser beams. 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 system consists of a laser shutter and a shutter controller that allows to drive the shutter in different modes of operation. The lass ii system enhances the signal to noise ratio of the laser over a broad bandwidth. However for specific installations or lasers we offer adaptations and additional modules which further help to optimize the system for relevant parameters. The compact system leads to a reliable and very precise beam position and direction stability and it compensates disturbances.

Description conoptics laser stabilization system lass ii is designed as an electro optic feedback loop capable of reducing the amplitude variations commonly associated with lasers. It is characterized by its straightforward handling and integration. Mrc systems offers medical products mri compatible video cameras and laser stabilization systems we develop laser optic electronic and medical products since 1995. A high speed field programmable gate array fpga is used as real time controller which makes the closed loop control period of only 4 175μs and response time for stabilizing process less than 90μs.

An innovative and practical scheme of building laser power stabilization system is proposed by using external control method. 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. The steering mirror thorlabs kc1 pz piezoelectric mirror is placed at the exit port of the first amplifier which is controlled by the motor driver thorlabs mdt693. Thus the shutter can be controlled automatically by other devices or semi manually with a safety confirmation by the user.
