Laser beam shaping techniques [PDF]
Proceedings of SPIE, 2000 Industrial, military, medical, and research and development applications of lasers frequently require a beam with a specified irradiance distribution in some plane. A common requirement is a laser profile that is uniform over some cross-section. Such applications include laser/material processing, laser material interaction studies, fiber injection ...

Laser beam shaping for surgery and microbiopsy
, 2022 Lasers are increasingly being used in surgery in a wide range of medical specialties due to their advantages over alternative surgical tools including precise material removal, limited bleeding due to coagulation around the incision site, and delivery through optical fibers enabling use in body cavities and for minimally invasive surgeries ...

Ray mapping approach in double freeform surface design for collimated beam shaping
, 2022 Paper 995004, 8 S.Laser beam shaping enables the simultaneous redistribution of the irradiance and phase of a laser beam. The desired shape of the laser beam is thereby determined by the respective application.

Anamorphic Shaping of Laser Beams [PDF]
PhotonicsViews, 2019 AbstractAnamorphic beam shaping optics are, e.g., used to transform elliptical laser beams to a round shape before coupling them to single‐mode optical fibers. Conversely, there are cases where originally round laser beams need to be transformed into an elliptical shape.
