Abstract: In one example, an on-mirror adaptive optics system may include a substrate including a deformable surface, a controller and a plurality of pockets defined in a substrate. Each of the pockets may include a an electrooptical sensor and an actuator. The controller may be communicatively coupled to the electrooptical sensor and the actuator. The controller may be configured to generate control voltages based on signals received from the electrooptical sensor to deform a portion of the deformable surface proximate a corresponding pocket of the plurality of pockets.

Abstract: A sensing method for in-situ non-perturbing measurement of characteristics of laser beams at the exit of the laser beam delivery fiber tips include measuring power of a laser beam transmitted through delivery fiber tip in fiber-optics systems. A sensing devices for in-situ non-perturbing sensing and control of multiple characteristics of laser light transmitted through light delivery fiber tips includes a fiber-tip coupler comprised of a shell with enclosed delivery fiber having a specially designed angle-cleaved endcap and one or several tap fibers that are specially arranged and assembled at back side of the endcap and other variations. Methods and system architectures for in-situ non-perturbing control of characteristics of laser beams at the exit of the laser beam delivery fiber tips include fiber-tip couplers and sensing modules that receive laser light from tap fibers, and systems for optical processing to enhance light characteristics suitable for in-situ measurement.

Abstract: The invention includes a deformable mirror for use in adaptive and active optical systems and in optical technology laser communication directed energy systems. The invention utilizes pockets formed in the back of the mirrors substrate. The pockets house actuators that are bonded to the substrate and may adjustably deform the mirror surface depending on the voltage supplied to the actuators. A plurality of mirrors may be combined to form a scalable array or positioned to overcome issues related to the uncontrollable portions of separate individual mirrors.
