Adaptive Optics (AO) dramatically improve the performance of optical systems by mastering wavefront distortions to deliver optimal focus and quality imaging for both scientific and industrial applications.
The principle of an AO optimization for UHIL is that a deformable mirror combined with a wavefront sensor and the appropriate software addresses all the requirements for either closed or open loop setups, and correct wavefront defects that inevitably affect UHIL beams.
The first step in such settings consists in measuring the wavefront with a sensor that features high accuracy, linearity and dynamic range in order to determine optimal corrections. The appropriate software should then not only gather all the data needed for the diagnostic part but moreover enable for the configuration of the interactions matrix that controls the deformation of the mirror, and makes the whole system perform optimally.
From that point the AO loop – i.e. the wavefront sensor / software / deformable mirror combo – will ensure that the UHIL beam is permanently optimized and delivers (the right intensity with the right shape at the right place) high Strehl-ratio focal spot to the right plane. Imagine Optic has been helping UHIL teams all over the world for the past 10 years, and most recently equipped all 6 beamlines of ELI – NP project that is currently ongoing in Romania, and recently reached record power level of 10.3PW.
