Simulation and experimental investigation on the wavefront correction performance of a dual magnetic connection deformable mirror under high-power laser irradiation

چکیده
Deformable mirrors (DMs) are widely used in high-power laser systems to improve the output beam quality. However, under irradiation, heat accumulates on DM mirror surface and results induced distortions (LID), which will degrade wavefront correction performance of DM. In order suppress negative impact LID DM’s performance, we introduce dual magnetic connection (DDM), base connected by two-layer magnets. Configuration DDM is presented. The simulation established analyze characteristics as well DDM. An experiment investigate practical conditions. Simulation indicate that could effectively maintain good capability.

High resolution wavefront correction with photocontrolled deformable mirror.
We demonstrate that a novel actuation scheme, employed in an optical control deformable mirror, can be more convenient than the conventional discrete fixed actuators approach. The Photo-Controlled Deformable Mirror (PCDM) mirror leverages consumer LCD display technology in the wavefront forming control, enabling flexible programmable configuration of the actuation geometry. This new approach si...
متن کاملLiquid deformable mirror for high-order wavefront correction.
We propose and demonstrate a novel liquid deformable mirror, based on electrocapillary actuation, for high-order wavefront correction. The device consists of a two-dimensional array of vertically oriented microchannels filled with two immiscible liquids, an aqueous electrolyte, and a viscous dielectric liquid, where the dielectric liquid overfills the top end of the channel and forms a thin lay...
متن کاملWavefront-aberration sorting and correction for a dual-deformable-mirror adaptive-optics system.
Many next-generation adaptive optics (AO) systems for vision will have two deformable mirrors (DMs) instead of one: a high-stroke, low-resolution mirror (the woofer) and a low-stroke, high-resolution mirror (the tweeter). We developed a zonal wavefront-control algorithm and validated it using simulations. Rather than separating the woofer and tweeter corrections into two independent control pro...
