Beam-by-beam Kerr clean-up in multimode optical fibres – INVITED [PDF]
EPJ Web of Conferences, 2023 We propose and demonstrate the concept of beam-by-beam cleaning in multimode optical fibres, i.e., the increase of the spatial quality of an intense laser beam, induced by a relatively weak, quasi singlemode seed beam.

Generalized beam quality factor of aberrated truncated Gaussian laser beams [PDF]
Journal of the Optical Society of America A, 2011 We outline a theory for the calculation of the beam quality factor of an aberrated laser beam. We provide closed-form equations that show that the beam quality factor of an aberrated Gaussian beam depends on all primary aberrations except tilt, defocus, and x-astigmatism.
