“…Recent advancements in laser beam shape engineering employing electronically controlled spatial light modulators (SLMs) [1][2][3], anamorphic optical systems [4][5][6], as well as coherent beam combination based on optical phased array (OPA) principles [7][8][9] have resulted in a variety of structured laser beam shapes. When applying existing industry techniques for the characterization of beam propagation characteristics, such as beam size, results may raise some reasonable questions justifying a closer look at the problem.…”

The paper presents the propagation characteristics of several complex laser field distributions. It also outlines the challenges associated with characterizing laser fields based on their M 2 parameter. To alleviate the challenges, we introduce a new beam characterization technique for defining the propagation characteristics of arbitrary laser beams. The new technique is based on calculating laser beam propagation characteristics as a function of the field's lateral coordinates, and provides a quantitative way of accounting for the fractional beam power diffracted outside of the beam central node. The technique, called FM 2 (FM-squared), accounts for the spatial evolution of the M 2 beam quality parameter. It provides insights into the beam quality of laser beams, including the quality of laser beams affected by diffraction or by wavefront distortions, as well as the complex field distributions resulting from a coherent superposition of the individual beams contained within optical phased arrays.

This protocol articulates an ongoing PhD thesis in Laser Art as an independent artistic trend including its history, classification criteria, philosophical and aesthetical aspects. Via several analytical studies theoretically and practically, the thesis is going to prove that laser art actively contributes, as an independent artistic trend, to change the conceptual definition of the artistic material. On the other hand, it bridges the gap between the artistic context and the technical issues, in which the conceptual values became fully integrated into the physical properties of the medium (laser beam), therefore it became impossible to separate the idea and the material of the artwork from each other. Besides, the thesis reveals the potential hidden conceptual and philosophical dimensions of the holographic art as one of the most important branches of laser art. In advanced step, the research suggestes a new model of interactive holographic art based on neural controlling system, and how this advanced approach can lead us towards a new kind of the aesthetic values, in which participants effectively contribute neurologically to constituting the artwork.
