AB  - Interakcija lasera sa materijalom je već dugo godina aktuelna sa mnogo rešenja, koja su postala komercijalna i gde se i ne stavlja u prvi plan da je reč o laserskom izvoru. To se utapa u elionska rešenja i poređenja delovanja snopova plazme, vode, neutrona, mikrotalasa. Razvijaju se osnovni teorijski i prakrtični evaluirani modeli. U modeliranju, modeli se dalje razvijaju, često se odmah prelazi na numeriku i u zavisnosti od energije / snage, repeticije radne laserske stanice, mogu se birati aproksimacije. U radu će se na osnovu eksperimentalnih izlaganja snopovima formirati niz pretpostavki o predviđanju i  krojenju svojstava starog materijala mogućim novim, izazvanim modifikacijama različitim tehnikama. Posebno će se razmotriti i slučajevi gde se ne zanemaruju efekti uzmaka i ovaj pristup je takođe prikazan, kao i sprega sa akustičnim pojavama. Svojstva materijala biće pokrivena novim spektroskopskim podacima, odnosno komparativnošću ili sagledavanjem materijala iz različitih uglova gledanja, pri čemu podudaranje / nepodudaranje sa teorijskim prilazom, samo po sebi, daje novi pogled na materijale. S druge strane, traže se paralelni procesi koji su prisutni tokom interakcije , ali usled pojave nelinearnih efekata pri većim intenzitetima dolazi do promene mesta raznih pragova za njihovo nastupanje (kao stimulativni procesi, indukovani, i koji se pojavljuju pored spontanih). Kako se i sam lasing pojavljuje kao deo interakcije stimulisane svetlosti / zračenja sa materijalom, posmatra se i pitanje  koeficijenata korisnog dejstva lasera i pragovi lasing-а. Postavlja se i paralela interferometrija / holografija / tomografija sa atributom laserska. Izveli smo naše simulacije za neke od procesa interakcije / rasejanja i eksperimentalne ekspozicije različitim tipovima lasera.
AB  - The interaction of lasers with material has been current for many years with many solutions,which have become commercial and where it is not brought to the fore that it is a laser source. It is drowned in elion solutions and compares the effects of plasma beams, water, neutrons, microwaves. Basic theoretical and practical evaluated models are developed. In modeling, models are further developed, often immediately switching to numerics and depending on the energy /power, repetitions of the working laser station, approximations could be chosen. In the paper, on the basis of experimental exposures to beams, a series of assumptions will be formed about the forecast and tailoring of the properties of the old material with possible new ones, caused by modifications with various techniques. Special consideration will also be given to cases where the effects of recoil are not neglected and this approach is also shown, as well as coupling with acoustic phenomena. The properties of materials will be covered with new spectroscopic data, or the comparability or seeing of materials from various angles of view, where matching / non-matching with the theoretical approach, in itself, gives a new view of materials. On the other hand, parallel processes are sought, which are present during the interaction, but due to the appearance of non- linear effects at higher intensities, there is a change in the place of various thresholds for their occurrence (as stimulating processes, induced, which appear in addition  to spontaneous ones). As lasing itself appears as part of the interaction of stimulated light /radiation with the material, the question of the coefficients of the useful effect of the laser and the thresholds of lasing is also observed. Parallel interferometry / holography / tomography with laser attribute is also set up. We performed our simulations for some of the interaction / scattering processes and experimental exposures to different types of lasers.

AB  - Mnogobrojni metodi transformacije energije, koji se danas koriste praktično u mass media i istraživanjima u raznim savremenim disciplinama zaslužuju analize sa nekoliko aspekata. Jedan od aspekata praktične prirode je poboljšanje karakteristika konstruisanih /ostvarenih senzora i komponenata u praksi, a drugi pitanje transformacije energije i filozofski posmatranog ,,pozitivnog ili negativnog pravca’’. U radu se analiziraju odabrani problemi i problematike, sa teorijske i praktične tačke gledišta, potkrepljene i eksperimentalnim pristupom.
AB  - Versatile methods of energy transformation, among which some of them currently are used even in mass media and in researches at different contemporary disciplines, deserve further analyzing from few aspects. One of the practical approaches is improving the characteristics of designed sensors or components which are present in praxis, while the other is the question of transforming of energy, as some would to say ''from the philosophical view as positive or negative direction“. In this paper are analyzing the chosen problems from the theoretical and practical view points.

AB  - The paper presents a brief overview of contemporary ELION techniques with stress on their use for material modification and dozimetry. In the attempt to avoid some common misjudges of irradiation effects, special attention is paid to exact definition of irradiation geometry and careful adjustment of dose rates, which en able a proper elaboration of experimental results. In particular, effects of γ -rays irradiation on properties of commercial optical fibres, splitters, connectors, and fibre joints are examined, which enables monitoring of irradiation effects in complex configurations made of materials with different radiation hardness (resistance). It has been established that γ -rays irradiation of the investigated elements influences, in different ways, the transmission of laser beam signals of various wavelengths, under different modulation regimes. After irradiation, the signal attenuation is noticeably larger, both in optical connectors and optical splitter, than be fore it, and the effect in creases in time. The effects are more pronounced at the 99 % than at the 1 % Y-splitter out put at both measured wave lengths, and are more pronounced at 1310 nm than at 1550 nm.
AB  - Rad predstavlja kratak osvrt na elionske tehnike sa akcentom na njihovoj upotrebi za modifikaciju materijala i dozimetriju. U pokušaju da se izbegnu neka uobičajena, pogrešna mišljenja o efektima zračenja, posebna pažnja je posvećena tačnoj definiciji geometrije zračenja i pažljivom prilagođavanju jačine doze, koji omogućavaju pravilnu obradu eksperimentalnih rezultata. Posebno su ispitivani efekti ozračivanja gama zracima komercijalnih optičkih vlakana, optičkih račvi, konektora i spojeva fibera, što omogućuje praćenje efekta ozračivanja na kompleksne konfiguracije uređaja od materijala sa različitom radijacionom otpornošću. Nađeno je da ozračivanje ispitivanih elemenata gama zracima na razne načine utiče na transmisiju signala – laserskih snopova različitih talasnih dužina i pod raznim efektima modulacije. Posle ozračivanja, slabljenje signala je znatno veće i kod optičkih konektora i kod optičke račve, nego pre njega, a efekat raste sa vremenom. Efekti su mnogo izraženiji kod 99 %, nego kod 1 % izlaza Y račve na obe merene talasne dužine, i više su izraženi na 1310 nm, nego na 1550 nm.
