摘要

We present the generation of the nanosecond cylindrical vector beams (CVBs) in two-mode fiber (TMF) and its applications of stimulated Raman scattering. The nanosecond (1064 nm, 10 ns, 10 Hz) CVBs has been directly produced with mode conversion efficiency of ~18 dB (98.4%) via an acoustically-induced fiber grating (AIFG), and then the stimulated Raman scattering signal is generated based on the transmission of the nanosecond CVBs in a 100-meters length TMF. The transverse mode intensity and polarization distributions of the 1st-order Stokes shift component (1116.8 nm) is consistent with the nanosecond CVBs pump pulse.
