Abstract

Development of methods for generating of laser beams with predetermined values of intensity and angular momentum distributions is a challenge of great interest for various laser technologies including laser manipulation by microscopic objects. The suggested method oftransformation of laser radiation to complex structure modes in build-up beam rotator interferometer has been theoretically evolved and experimentally tested. Its main advantage over the others is that the method doesn't require complex diffractive optical elements to be used. Experiments were performed using tunable (adjustable) diode laser and interferometer formed by three mirrors. The beam rotation has been achieved by Dove prism inserted into the interferometer. The evolution of the transformed beam was observed with alternation of the prism rotation angle and the injection current of the laser diode.
