Laser Beam Stabilization System

The laser shutter system beamblockis designed for blocking high power laser beams.

Laser beam stabilization system.

Laser beam stabilization compact stand alone system for an easy installation to the laser beam path. The basic configuration of the compactsystem is fully equipped for stabilization tasks in laser machines. However for specific installations or lasers we offer adaptations and additional modules which further help to optimize the system for relevant parameters. 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.

Guarantees critical alignment of complex systems convenient gui for user friendly operation trigger kit available for lower laser repetition rates. The system consists of a laser shutter and a shutter controller that allows to drive the shutter in different modes of operation. Thus the shutter can be controlled automatically by other devices or semi manually with a safety confirmation by the user. 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.

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. Andreas velten created date. It is characterized by its straightforward handling and integration. An innovative and practical scheme of building laser power stabilization system is proposed by using external control method.

The lass ii system enhances the signal to noise ratio of the laser over a broad bandwidth. 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 compact system leads to a reliable and very precise beam position and direction stability and it compensates disturbances. 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.
