State-of-the-Art Technologies in Piezoelectric Deformable Mirror Design

Abstract: In this work, two advanced technologies were applied for manufacturing a bimorph wavefront corrector: laser ablation, to vaporize conductive silver coating from piezoceramic surface, and parallel-gap resistance microwelding, to provide a reliable electrical contact between the piezodisk surface silver electrodes and copper wires. A step-by-step guide for bimorph mirror production is presented, together with the ‘bottlenecks’. Optimization of the laser ablation technique was carried out using an Nd:YAG laser wi… Show more

“…This problem has been studied for more than a dozen years, yet has not lost its relevance. The technology for increasing the efficiency of laser radiation transmission to the receiver includes two main components: high-quality efficient single-mode laser radiation sources and adaptive optical systems for correcting for wavefront aberrations [37,38]. In this research, we will concentrate on the second component.…”
