OPTIMAL Project – Development of a Dual-Technology Tip/Tilt Adaptive Optics System for High-Energy Lasers (HEL)

In the development of laser systems, energy 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 led by CTEC for the French Defence Procurement Agency (DGA) will provide with a cost-effective adaptive tip/tilt optics’ solution, derived from its FSM for space-based laser communication. On one hand, the innovation lies 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 Direct energy weapons (DEW), the thermal management due to mirror and piezoelectric ceramic heating as well as precise control at high frequency and large amplitude.

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