The Optonics Multilayer Dielectric Grating (MLD Grating) is a high-performance optical component engineered for high-power laser applications, including Spectral Beam Combining (SBC) systems.
The MLD grating features a precision diffraction grating structure formed on a dielectric multilayer reflector. The dielectric multilayer is fabricated on the substrate using ion beam sputtering (IBS), delivering exceptionally low optical absorption and a high laser damage threshold, essential for high-power laser operation.
To form the grating structure, Optonics employs advanced nanoimprint lithography and reactive ion beam etching, enabling high pattern fidelity, excellent uniformity, and scalable manufacturing. This process capability allows rapid customization across a wide range of wavelength bands and grating densities, meeting diverse system requirements.
