Design of a Doubly Grooved Binary Metallic Diffraction Grating For Efficient Side-Pumping of High-Power Fiber Lasers

摘要：

A metallic binary grating with two grooves per period is applied to side-pump high-power fiber lasers for the first time. By combining a gradient algorithm and micro-genetic algorithm, the grating is optimized and the maximum coupling efficiencies of 94.77％ and 77.27％ for TM and TE polarization waves respectively are demonstrated.
