主　　题：acoustically induced fiber grating LP_(11)mode mode decomposition random distributed feedback Raman fiber laser 

摘      要：An all-fiberized random distributed feedback Raman fiber laser(RRFL)with LP_(11) mode output at 1134 nm has been demonstrated experimentally,where an intracavity acoustically induced fiber grating is employed for modal *** maximum output power of LP_(11) mode is 93.8 W with the modal purity of 82%,calculated by numerical mode decomposition technology based on stochastic parallel-gradient descent *** our best knowledge,this is the highest output power with high purity of LP_(11) mode generated from the *** work may pave a path towards advanced fiber lasers with special temporal and spatial characteristics for applications.
