A unique deformable mirror
ILAO Star (Intense Laser Adaptive Optics) is the most advanced deformable mirror available that is specifically designed for today’s ultra intense and ultra-fast lasers. Based on Imagine Optic’s patented technology, ILAO Star operates using mechanical actuators with astatic floating heads that perform wavefront shaping with nanometric precision. Depending on the type of laser, users can choose from replaceable dielectric or metallic reflective surfaces from 20mm up to 500 mm in diameter.
Once the optimal mirror shape has been achieved, power is no longer necessary to maintain ILAO Star’s form. The fact that the mirror no longer dissipates any energy or heat from its interior ensures that its high optical quality
surface (<10 nm rms) maintains a perfectly stable form over time and minimizes the risk of unwanted hotspots.
Wavefront correction and beam control
ILAO Star is the wavefront correction element of the full-featured adaptive-optics solutions that Imagine Optic provides for ultra-intense and ultra-fast lasers. When combined with a HASO4 wavefront sensor and our WaveTune command & control software, you have a turnkey solution, where each element works together seamlessly via one ergonomic interface. Our Phase Retrieval algorihm PhaRAO is also available in WaveTune as an optional module. With the help of a simple CCD camera, PhaRAO enables users to control and optimize the focal spot directly in the interaction chamber.
