Paper Abstract

The paper presents a report on our current work on obtaining the analytic functions of the laser impulses generated by optical choppers with disks in their classical configuration - with windows that have linear margins. With regard to our previous researches, focused on choppers working with top-hat (i.e., with constant intensity) laser beams, in the present work Gaussian laser beam distributions of the light beams to be chopped have been considered, for the most common case, of a light bundle of a sufficient small diameter in the plane of the disk; this type of section can therefore be completely obscured and uncovered by the chopper wings and windows, respectively. The functions of the transmitted light flux of the device are approached. This allows for the designing calculus of choppers for different applications, taking into account their specific requirements. A comparison between analytical results obtained in this work and results from our previous numerical modeling is pointed out.
