Fast and efficient manufacturing method of one‐ and two‐dimensional polyethylene terephthalate transmission diffraction gratings by direct laser interference patterning

Abstract

One‐ and two‐dimensional diffraction gratings were fabricated on commercial polyethylene terephthalate (PET) film by two beam direct laser interference patterning (DLIP) method using a pulse laser (10 ns) with a wavelength of 266 nm. The relative diffraction efficiency of the structured specimens (at 633 nm) in transmission mode was measured and correlated with the topological characteristics of the structured PET substrates. The obtained diffraction gratings made by DLIP show better or similar diffraction efficiencies when compared with the reported efficiency of gratings made by other methods (up to 42.5% for 1 μm arrays), and can be fabricated on large areas in very short processing times (up to 18 cm2/s).

Label-free detection of C-Reactive protein using bioresponsive hydrogel-based surface relief diffraction gratings

“…technology. 47 For this work, a frequency quadrupled Q-switched laser head (Laser-export Co. Ltd., TECH-263 Advanced) with a maximum pulse energy of 50 µJ and operating at a wavelength of 263 nm and a pulse duration shorter than 3 ns was used. The laser beam has a Gaussian intensity distribution (TEM00) with a beam quality of M 2 < 1.3.…”
