8 October 2012 www.newport.com A Simple, Automated, Cost-Effective Solution to Beam Stabilization and Optical Alignment Recovery As a single point provider of motion control hardware, opto-mechanics, photonic instrumentation and optics, Newport is uniquely positioned to provide easily integrated, cost-effective beam alignment and stabilization tools with CONEX and Agilis technology. Beam stabilization is ideal for CW and pulsed laser systems with position drift and pointing angle instability. Adding a second correction loop or module, both pointing angle and beam position drift can be corrected. In this configuration, two loops can be configured sequentially with the optical path from the first corrective loop entering the next corrective loop. In both configurations, the optical path is not pre-determined and can be customized for easy modular integration with your optical setup. The software does not require a preferred configuration and the motorized mirror will always be programmed to correct to the sensor’s center position. Newport Motion offers a wide selection of motorized positioning solutions and the integration of CONEX and Agilis motorized optical mounts in the beam stabilization setup was carefully considered for dynamic performance, in-position stability, compact, modular construction and cost. The compact, modular and cost-effective approach to beam stabilization is intuitive and easy to use, robust, configurable, easily integrated in your preferred optical path and can operate with a variety of laser sources. Driven by Newport Motion technology, beam stabilization can be configured and built by the customer with intuitive use and automation provided by a CONEX-BeSt Software. A P P L I C A T I O N Basic Setup The beam stabilization setup uses a closed-loop optical path with a motorized mirror mount and integrated beam splitter. The beam splitter divides the beam into a transmitted portion and a pick-off path passed to a position sensing detector (CONEX-PSD9). CONEX-BeSt software sets up a real-time control loop commanding the mirror to compensate for angular pointing errors and returns the beam to the fixed reference at sensor center. This naturally, keeps the transmitted beam in the optical path and automatically compensates for angular instability from the laser source or other environmental factors. CONEX-BeSt software provides a real-time display which actively follows the beam position with point tracing for monitoring alignment stability. Not only is the beam position provided, but also relative laser power measurements are displayed as well. Beam stabilization can be activated or disabled at any time via software front panel.
