Thessmovism analysis of developed temperatures on different types of materials and dependence on the wavelength of the incidental laser beam

U primeni koherentnog zračenja za dijagnostiku i čišćenje materijala od nataloženih slojeva sa objekata od značaja za kulturnu baštinu, koristi se nekoliko tipova lasera od kojih neki imaju po više izlaza. Nd3+:YAG laser (jednog sistema) se koristi na izlazima: 1,06 μm, 532 nm i 355 nm. Izabrani uzorci materijala različite prirode (keramike, papira, plastike, metala) su izlagani dejstvima prva tri izlaza u cilju uklanjanja neželjenih slojeva. Modeli su predstavljali objekte za procese u kojima se skida željeni sloj sa probnog uzorka tipa grafita, hemijske olovke, flomastera i markera. Pri svakom izlaganju, sniman je odgovarajući termovizijski zapis tako da postoji mogućnost provere modelovanja interakcije odabranog snopa sa materijalom i provera temperaturne distribucije putem simulacija analitičkim i numeričkim metodama sa raznim paketima programa (Numerics, Comsol, Zemax, Glad..).In the application of coherent radiation for diagnostics and cleaning materials from the contaminated layers from the facilities of relevance to cultural heritage, several types of lasers are used, some of which have several outputs. ND3 +: YAG LASER (one system) is used on the outputs: 1.06 μm, 532 nm and 355 nm. Selected samples of materials of different nature (ceramics, paper, plastic, metals) are exposed to the effects of the first three outputs in order to remove unwanted layers. The models represented objects for processes in which the desired layer from the trial sample type of graphite type, ballpoint pen, flomaster and marker is removed. In each presentation, the corresponding thermal imaging is recorded so that there is a possibility of checking the interaction of the selected beam with materials and checking temperature distribution through simulations of analytical and numerical methods with various packages (Numerics, COMSOL, ZEMAX, HLAD ..)
