Polarization insensitive diffraction grating for Navy tactical airborne high energy lasers (HEL) applications

LightSmyth is a US based manufacturer of high power high efficiency polarization insensitive diffraction grating using unique, cost-efficient and high fidelity manufacturing technology. Gratings are etched into fused silica substrate and contain no organics or polymers. They may be as large as 150 mm in diameter with clear aperture up to 135 mm. LightSmyth is uniquely positioned to supply Navy with requested grating for high energy laser with minimum technical risks, at a fraction of the solicited price and with superior performance. LightSmyth already has gratings that approach the requested performance and only small design modification and performance verification will be required to fully meet them.
