“…Moreover, further generation of cylindrical vector beams and vortex beams based on HOMs has also been verified [3][4][5][6][7][8][9] , which finds a tremendous range of applications, including plasmon excitation [10] , optical tweezers [11] , and electron acceleration [12] . So far, several routines to achieve HOMs have been confirmed, such as specially designed fibers [13,14] , lateral offset splicing [15] , long-period fiber gratings (LPFGs) [16][17][18] , few-mode fiber Bragg gratings (FMFBGs) [19][20][21][22] , mode-selective couplers (MSCs) [4,[23][24][25][26][27] , spatial light modulators [28][29][30][31][32] , active polarization control [33,34] , and acoustically induced fiber gratings (AIFGs) [35][36][37][38] .…”

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 switching. The 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 algorithm. To our best knowledge, this is the highest output power with high purity of LP 11 mode generated from the RRFL. This work may pave a path towards advanced fiber lasers with special temporal and spatial characteristics for applications.
