Title: SYSTEM FOR IMPROVING THE LASER DAMAGE THRESHOLD OF MULTILAYER DIELECTRIC GRATINGS
Abstract:
A system configuration that significantly improves the laser damage threshold of multi-layer dielectric gratings for lasers applications includes three main sections: 1) a laser module, 2) a TM polarization module, and 3) a multi-layer dielectric grating optimized for high efficiency operation with transverse magnetic polarized laser light.
