Abstract

We have developed a high resolution programmable adaptive optic device based on an optically-addressed liquid crystal electro-optical valve (OALEV) controlled by an achromatic three-wave lateral hearing interferometer (ATWLSI). This loop, which can work at 4 Hz, corrects the wavefront of our 100-TW Nd:Glass. Beyond this application, we were able to generate high resolution programmable phase plates to shape the far- field pattern of low-energy cw-lasers as well as high power lasers.
