OASys: Adaptive optic loops

Adaptive Optics Solutions that Fit Your Laser Beam diagnostic

PhasicsTM adaptive optics solutions allow getting the highest intensity out of your laser beam. For imaging systems, we ensure diffractive limited performances.
The OASys product line combines our high performance SID4 wavefront sensor to a beam shaper best suited to your application.

Adaptive Optics loop with OASys

Thanks to our experience in adaptive optic loops installation, we advise you on the correction choice adapted to your application :

  • deformable mirror (mirror size, damage threshol...)
  • spatial light modulator (in transmission or in reflexion...)
  • deformable membrane (size, positionning on the laser chain...)

OASys software is dedicated to control the correction device (deformable mirror, SLM or deformable membrane). It is linked to the SID4 main interface software.
After installation, we follow up on the adaptive optic loops. This customer service is greatly appreciated by the SID4 wavefront sensor and OASys users that are supported in their experiments.

Focal spot optimization

By correcting wavefront distortion occurring on high power laser chains, you couple all your laser energy to matter and reach the highest peak intensity.

Focal spot shaping

Go beyond laser matter interaction with Gaussian or Airy disk far-field patterns by controlling the shape of your focal spots.

Wavefront sensor loops

Two SID4 wavefront sensor loops to control the shape of the beam before and after compression with dynamic cumulative thermal effects on a 100-TW laser facility (30J/300 fs).

Beam propagation optimization

Let the laser beam propagate from your laser source all the way to the end user without any distortion or get a M²=1 beam.

Beam shaping on a CW laser

A computer-generated phase mask is applied in order to shape the focal volume and dynamically extend the Rayleigh range from a few millimeters to a few centimeters. Get the highest resolution with the combination of the SID4 sampling and an optically addressed phase-only spatial light modulator (SLM).
