Tailoring light at the source: structured light from laser resonators

Not Accessible

Your library or personal account may give you access

Abstract

Here we outline the various approaches to creating structured light directly from a laser cavity. By exploiting intra-cavity dynamic and geometric phase control, as well as complex amplitude modulation, a range of custom modes may be generated on-demand. Examples of experimentally created modes include flat-top beams, vortex beams and general Poincare beams.
