Water-cooled stacked-actuator deformable mirror for atmospheric applications
Optical Engineering + Applications, 2019High-power laser systems are widely used for technological purposes or laser fusion experiments, but also to deliver the energy to some remote places here on the Earth as well as in space.

Unimorph deformable mirror for telescopes and laser applications
International Conference on Space Optics — ICSO 2010, 2019Over the past 5 years we have developed a new type of unimorph deformable mirror. The main advantages of this mirror technology are • very low surface scattering due to the use of super polished glass • excellent coatings, even suitable for high power la

Fully Organic Photocontrolled Deformable Mirror
Advanced Optical Materials, 2018AbstractA light‐driven deformable mirror based on an organic photoconductive layer is designed and realized. The requirements for the photoconductive organic material are reported showing their effect on the mirror performances. The production and characterization of the photoconductive thick layer consisting in a polystyrene matrix doped with P3HT ...

LC phase modulator vs. deformable mirror for laser beam shaping: What is better?
Optical Engineering + Applications, 2018The latest results on intensity distribution transformation from Gaussian to a flattop and doughnut are presented in the paper. The wavefront was modified with bimorph deformable mirror to reach the desired intensity distribution in the farfield.

Push-pull electrostatic deformable mirrors
SPIE Proceedings, 2008Deformable membrane mirrors have a lot of advantages if compared with other adaptive optics devices such as bimorph mirrors, liquid crystal modulators, and thermal mirrors. Their properties are good optical power, low cost, limited power consumption, achromaticity and a good dynamic behavior. Their use in technological applications is limited by the
