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

Consideration on the use of design freedoms for resonator originated beam shaping
, 2022 S.69-73A general resonator concept is discussed offering the flexibility of decoupling the mode shape inside and the laser beam outside of the laser resonator. Two examples for the use of the resulting design freedoms for optimization of the laser system
