摘　　要：谱叠加技术是一种非相干叠加方法,采用色散元件来实现各单元光束的叠加。介绍了光栅法、受激布里渊散射法、布拉格体光栅法等3种谱叠加技术,分析了各自的工作原理并比较了3种方法的优缺点。Spectral beam combining, which employs dispersive elements to combine beams from every unit, is one of incoherent combining. Three kinds of spectral beam combining, grating method, stimulated Brillouin scattering method and Bragg volume grating method are introduced. The work principles are analyzed separately and the merits and shortcomings of them are compared.
