Grating waveguide structures (GWS) are reflective diffractive optical elements that operate based on the combination of sub-wavelength gratings (periodic microstructures) integrated with planar waveguides. They can be used for high-power laser applic

Publikováno v: 2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC).

Within the past decade, a variety of scientific groups have demonstrated the potential of radially and azimuthally polarized laser beams in many applications [1–3]. Experimental investigations in high-power operation indicate additional beneficial

Trimming method for a high-yield manufacturing of high-efficiency diffraction gratings

Autor: Benjamin Dannecker, Marwan Abdou Ahmed, Martin Rumpel, Thomas Graf

Publikováno v: Optics letters. 43(16)

The tolerances in manufacturing of fully dielectric diffraction gratings based on the leaky-mode resonance in the −1st diffraction order can be challenging, especially if the grating design exhibits high diffraction efficiency (DE) only within a co

Recent improvements in LIDT of optical components for pulsed and CW applications

Autor: Marwan Abdou Ahmed, Christian Grunert, Martin Rumpel, Lars Mechold

Publikováno v: Laser-Induced Damage in Optical Materials 2017.

Today the laser induced damage threshold (LIDT) is one of the most important properties of laser components. As laser systems reach higher and higher optical power densities, optical components with improved LIDT values are highly required and their
