Abstract

Išradimas yra susijęs su skaidrių medžiagų apdirbimo būdais, naudojančiais ultratrumpuosius lazerio impulsus. Medžiagų, žymia dalimi skaidrių lazerio spinduliuotei, apdirbimo būdas apima necentrosimetrinio nedifraguojančio pluošto suformavimą optiniame elemente, kuriame yra bent dvi dvejopalūžių struktūrų sritys, kai kiekvienoje tų sričių Pancharantnam'o-Berry fazė kinta pagal tai sričiai būdingą dėsnį. Praėjusios elementą šviesos energijos, fazės bei poliarizacijos skirstinių forma kinta, priklausomai nuo krentančios į elementą šviesos parametrų. Pluošto energijos skirstinys sukuriamas artutinai tolygus šviesos plitimo kryptimi. Lazerio impulso energija parenkama taip, kad ruošinyje sufokusuoto pagrindinio skirstinio maksimumo poveikio srityje susiformuotų pailgos tuštuminių pažaidų sritys norima kryptimi, o gretimų impulsų šalutiniai maksimumai paveiktų ruošinį, sukurdami cheminio pobūdžio pokyčius tarp gretimų impulsų pažaidų. Iš sukurtų pažaidų sričių ir cheminio poveikio sričių suformuojama norimos formos pjūvio linija. Taip apdirbtas ruošinys patalpinamas agresyviame tirpale, kuriame paveiktos sritys tirpsta žymiai sparčiau, negu nepaveiktos, dėl ko ruošinio medžiagoje galima gauti pjūvius su pločio ir gylio santykiu, siekiančiu 1/50.
