Generation of nanosecond cylindrical vector beams in two mode fiber and its appl

We present the generation of the nanosecond cylindrical vector beams (CVBs) in a two-mode fiber (TMF) and its applications of stimulated Raman scattering. The nanosecond (1064 nm, 10 ns, 10 Hz) CVBs have been directly produced with mode conversion efficiency of ~18 dB (98.4%) via an acoustically ind
