Paper Abstract

For high precision beam steering usually complex and sophisticated mechanics are necessary to keep the alignment long term stable. Here we present a simple temperature controlled steering device based on a crystal with different temperature expansion coefficients in its axes. Results for single mode fiber coupling of visible lasers will be presented.
