OPTIMAL Project – Development of a Dual-Technology Tip/Tilt Adaptive Optics System for High-Power Lasers

In the development of laser systems, power density on the target is the main challenge to overcome. Traditional adaptive optics are used to increase laser efficiency and address this need. Similar requirements exist in civilian manufacturing applications to improve the quality and speed of laser drilling, welding, or printing. The OPTIMAL project will provide a cost-effective adaptive tip/tilt optics solution, initially developed for space-based laser communication. The innovation lies on one hand, in the combination of two tip/tilt technologies: piezoelectric and magnetic Fast Steering Mirrors (FSM) arranged in series within a feedback-controlled optical loop, to compensate for turret defects and atmospheric disturbances. On the other hand, the project addresses technical and technological challenges related to FSMs, including: the integration of high-reflectivity mirrors for high-power lasers, thermal management due to mirror and piezoelectric ceramic heating, and precise control at high frequency and large amplitude.

The results of this project will be leveraged in defense through laser weapon performance simulations, and in the civilian sector through a piezo tip/tilt solution for high-power lasers, enabling increased industrial productivity for our clients.
