Amplification of orbital angular momentum beam in a fiber Raman amplifier
Amplification of orbital angular momentum beam in a fiber Raman amplifier
We experimentally demonstrate 6.5 dB amplification of an orbital angular momentum (OAM) beam through a co-pumped fiber Raman amplifier based on a commercial step-index few mode fiber. Preliminary estimate of mode purity upon amplification is 85%.

Abstract

We experimentally demonstrate 6.5 dB amplification of an orbital angular momentum (OAM) beam through a co-pumped fiber Raman amplifier based on a commercial step-index few mode fiber. Preliminary estimate of mode purity upon amplification is 85%.
