Optical Phase Aberration Correction with an Ultracold Quantum Gas

Understand

We present an optical aberration correction technique for ultracold quantum gas experiments which directly utilizes the quantum gas as a wavefront sensor.

• The direct use of the quantum gas enables correcting aberrations that are otherwise impractical to measure, e.g.
• introduced by vacuum windows.
• We report a root-mean-square precision and accuracy of 0.01{\lambda} and 0.03{\lambda}, respectively, and also show independently the reduction of aberrations through measurement of the trap frequency of our optical tweezer.
