“…Laser methods of PMMA treatment are considered in numerous articles from various points of view: simulations, experiments with different types of laser devices, industrial applications, material processing for optical components, cutting and shaping of panels, tropheys, fiber applications, etc. [3][4][5][6][7][8][9][10][19][20][21][22][23][24][25][26][27]. The part of the theory used in these descriptions is applicable also for the other transparent materials, composites, glassy and plastic materials.…”

“…Concerning the broad area of its applications, the vast of reference data can be found about the laser methods for PMMA shaping [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The optimization of laser systems working regimes, including the investigated of large variety of laser pulses going down to femtosecond duration were also performed, both theoretically and experimentally.…”

“…The plasma state was produced in PMMA using the UV laser, and interesting chemical processes were observed. It is also worth to underline simulation of different processes when various types of laser systems were used simultaneously, including some unconventional measuring methods [6][7][8][9][10][11][12][13][14][15][16][17].…”

Due to its excellent mechanical, chemical and optical properties, also on fatigue, polymethilmetacrylate (PMMA) is widely used for many purposes. PMMA has a reputation as a material that cannot be machined well, but, its elasticity and toughness enable its shaping by the deformation processes. Laser drilling and cutting are also available techniques for PMMA sheets shaping, used when both mechanical and optical PMMA properties must be preserved. In this work, the influence of CO 2 laser cutting/drilling on transparent and coloured PMMA surfaces is investigated, as well as by the other laser systems. The cut surfaces were investigated by a light microscopy and, on those surfaces, the average surface roughness R a was measured. The material zone affectted by the laser beam during the cutting process was monitored by a thermal imaging, and theoretical simulations of temperature distribution in this area were performed using the various versions of COM-SOL packages.

It seems that the role of lasers in heritology and art has grown more and more since the end of the 20h century; the early attempts of cleaning artistic objects, old monuments / artifacts during the times of Hedy Lamarr and the first unsuccessful nuclear tests as well as of thinking of holographic records. After the first series of circumstances linked to laser applications in restoration and conservation, it seems the coupling of words serendipity-zemblanity-bahramdipity has been activated. A long time has passed since the first works linked to the Porta della carte of the Palazzo Ducale (Doge's Palace) in Venice (marble relief and ruby laser). Nowadays, this type of work can be treated as standardized and it is implemented in great number of countries [1, 2]. In the case of Florence Cathedral, the conservation of artworks was proposed by J. F. Fonatello, panels of the Giotto's tower of the Florence Cathedral by Andrea Pisano. The unique roles of quantum generators - lasers - exist both in restoration and diagnostics. Besides that, the question of source existence - a source that provides completely new artistic impression with respect to its ideal characteristic of coherency - introduced new tools and techniques and could be (and was) implemented in many new processes and effects. New artistic directions were performed, where the source of the coherence became a part of a new artistic object, a hologram slide provokes the impression of the train entering the crowd, etc. [1-5] the laser role by using LIBS method in diagnostics in the case of the building in 7 Balkanska street, Belgrade, was presented in this paper.
