Abstract

Oglinda de interferenta cu reflexie înalta pentru mai multe benzi spectrale, conform inventiei, este utilizata în special atunci cînd intervine cea mai mica pierdere pentru lumina de la mai multe linii spectrale sub benzi spectrale puternic separate, fiind introdusa ca oglinda rezonator în laserele cu gaz cu mai multe lungimi de unda a laserului, pglinda ce cuprinde un strat de baza, pe care se aplica grupe de straturi alternative si care, între grupele de straturi alternative si care, între grupele de straturi alternative, învecinate, formate din doua pîna la noua straturi individuale, sunt dispuse unul sau mai multe straturi de cuplaje nemetalice, acordate pe aceeasi marime de lungime de unda lamda 0' în care straturile individuale ale tuturor grupelor de straturi alternative au o grosime optica de 1/4 din aceasta marime de lungime de unda lamda 0. Grosimea optica a straturilor de cuplaj nemetalice este un multiplu întreg de lamda 0/4. Marimea lungimii de unda lamda 0 este pentru aceasta lungime de unda medie a domeniului de utilizare spectrala, în care trebuie sa se gaseasca benzile de reflexie.The high reflection mirror of multiple spectral bands according to the invention is particularly useful when the smallest light loss occurs from several spectral lines under strongly separated spectral bands, being introduced as a resonant mirror into the gas lasers multiple wavelengths of the laser, the mirror comprising a base layer on which alternate layer groups are applied and which, between alternate layer groups and which, between adjacent alternative layer groups, formed from two to nine layers one or more layers of non-metallic couplings are arranged, provided on the same lamda 0 'wavelength, wherein the individual layers of all alternative layer groups have an optical thickness of 1/4 of this lamda wavelength 0. The optical thickness of the non-metallic coupling layers is an integer multiplicity of lambda 0/4. The magnitude of the lamda 0 wavelength is for this average wavelength of the range of spectral usage in which the bands of reflection must be found.
