Three-dimensional recording and structuring of chalcogenide glasses by femtosecond pulses

Juodkazis, Saulius; Kondo, Toshiaki; Rode, Andrei V; Matsuo, Shigeki; Misawa, Hiroaki


We report on three-dimensional (3D) holographic recording in As 2S3 glass using 800 nm wavelength, 150 fs duration pulses. Diffractive beam splitter was used to generate 2-5 beams which were then focused for recording by objective lens of numerical aperture NA = 0.75. The recorded 3D hologram was read out by diffraction of 632 nm HeNe laser beam confirming the expected pattern of holograms. The mechanism of photo-darkening and optical damaging of As2S3 glass and dielectrics in general is...[Show more]
