AOKit ILAO Star – Adaptive Optics for Intense Lasers
The AO kit ILAO Star is a complete solution adaptive optics kit for intense laser applications and an association of:
- HASO TM for a simple, precise and reliable measurement of the wavefront,
- ILAO STAR TM for a smooth and stable correction,
- WaveTuneTM for a total control of the operations, and
- PharAO for the ultimate correction.
Adaptive Optics (AO) improves the performance of optical systems by reducing the effect of wavefront distortions with the goal of delivering the best focusing or image quality for science and industry.
- HASO TM
HASO Shack-Hartmann wavefront sensor offers accuracy (lambda/100 rms), linearity (<0.1% linearity error) and dynamic range all together without compromise. This will allow to reach optimum corrections performance or the possibility to fully characterize a phase modulators.
- WaveTune TM
WaveTune addresses all the requirements for closed and open loop type of operations. It also offers advanced diagnostics and configurations of the interaction matrix which is a major step in the process of getting the AO system to perform.
- Wavefront modulators
ILAO Star intense laser adaptive optics kit 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.
SOFTWARE FOR FOCAL SPOT OPTIMIZATION
Phase Retrieval algorithm 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.
The phase retrieval algorithm processes the acquired data and calculates the differential aberrations between the wavefront sensor and the focal spot diagnostic camera. The result of these calculations is the differential aberrations of the system, i.e. aberrations that are present either on the wavefront sensor path or on the main laser path up, but not on both path (as those were corrected in the first step). Results are crossed checked by doing recalculation of the focal spot of calculated differential aberrations and checking that they are indeed similar to the acquired images of the focal spot. The phase retrieval algorithm has been optimized in terms of calculation speed. It can take several minutes for the usual algorithm to calculate a single wavelength. The optimized algorithm takes only a few seconds. This increase of speed is necessary in order to get the full correction within a few minutes even if several iterations of steps 2, 3 and 4 are necessary to get the perfect focus beam.
