LBSA: A GUI-based Matlab software for the advanced laser beam shaping with spatial light modulators
SoftwareX, 2023 We present LBSA — a complex laser beam shaping application that integrates the design and control features into a single graphical user interface app. This approach makes the advanced beam shaping operations accessible even for non-technical users.

Beam shaping using Gaussian beam modes [PDF]
Journal of the Optical Society of America A, 2010 A beam shaping method is presented where a diffractive optical element (DOE) is designed by optimizing the complex mode coefficient weights of a set of Gaussian beam modes. This method is compared with the more standard unidirectional approach. Differential evolution is used for the optimization in both the unidirectional and Gaussian beam mode ...

Flattop Beam Shaping Using Hybrid Gratings
IEEE Photonics Journal, 2022 A new method of laser beam shaping with hybrid gratings is presented. The hybrid gratings consist of a blazed grating and a gradient binary grating. The blazed grating is used to separate the incident Gaussian beam into zero order and nonzero diffraction
