Abstract
A new approach based on coherent beam combining of radiation emitted by an array of phase controlled fiber lasers in the far optical field is studied theoretically and experimentally. In this case, the resultant intensity distribution is formed as a result of combining and interference of wave fields of subbeams and determined by controlled phase relations between subbeams. The feasibility of forming a preset spatial profile of radiation in scalar and vector synthesized beams characterized by the inhomogeneous local intensity distribution (structured radiation) is considered, and promises for further investigations are outlined. The concept of a versatile “digital laser” is formulated.
