This study introduces a new method using two deformable mirrors to clean up laser beams, significantly improving focus quality beyond single-mirror limits. The advanced adaptive optics system achieves a 3.0 times diffraction-limited beam quality.

Area of Science:

  • Adaptive Optics
  • Laser Beam Cleanup
  • Wavefront Sensing and Control

Background:

  • Single deformable mirrors struggle to correct complex wavefront aberrations in laser systems.
  • Advanced beam cleanup is crucial for applications requiring high-quality laser beams.
  • Wavefront-sensor-less adaptive optics offer an alternative to traditional Shack-Hartmann sensors.

Purpose of the Study:

  • To develop and validate an optimization-based correction method for controlling two deformable mirrors simultaneously.
  • To address limitations of single-mirror systems in compensating for significant wavefront aberrations.
  • To enhance laser beam quality in a wavefront-sensor-less adaptive beam cleanup system.

Main Methods:

  • Implemented an optimization-based control strategy using the stochastic parallel gradient decent algorithm.
