ILAO STAR – High power deformable mirror

ILAO STAR is the first mechanical deformable mirror that was developed for applications in Ultra High Intensity Lasers. Based on a patented actuation technology, ILAO operates using mechanical actuators with astatic floating heads that perform wavefront shaping with nanometric precision, extremely high repeatability and perfect linearity.

This high power deformable mirror provides extremely low residual errors on its full dynamic range and allows performing correction without high spatial frequency phase modulations to prevent damages on downstream optics. It is compatible with most available metallic and dielectric coatings and can be customized to match with integration at 45 degree and square beams.

Key specifications

– Optical quality enabling Strehl Ratio > 0,9
– Closed-loop processing frequency ≥ 10Hz
– Very low hysteresis (less than 0.5%)
– Very high correction capability
– No backlash compensation needed
– Completely customized to laser’s parameters
– Easy maintenance for actuator or substrate replacement
– Any angle of incidence ≤ 45°

Key features

– Mirror shape maintained even without electrical power
– Excellent optical quality with active flat better than 10 nm rms and minimal print-through effect
– Perfectly adapted to a beam diameters ranging from 20 to 500 mm
– Dielectric, metallic, or hybrid coating available
– Compatible with WaveTune software and every HASO wavefront sensors
– Optional SDK in C, Python, Labview

Moreover, its integration in the Laser before or after the compressor allows providing a corrected wavefront before the beam transportation. For the correction of the beam transportation, Imagine Optic has developed PHARAO, a software using the focal spot itself to determine the non-common path aberrations and perform ultimate correction for diffraction limited focusing on target.

The amount of energy, beam diameters and safety standards have largely increased to meet new scientific challenges in inertial confinement fusion, plasma acceleration and particle physics experiments.  The level of performance and maintenance features offered by ILAO STAR deformable mirror perfectly meets the highest requirements of actual laser installations.
