Fiber amplification of radially and azimuthally polarized laser light

TL;DR

This paper demonstrates that fiber amplifiers can effectively amplify radially and azimuthally polarized laser light while maintaining high polarization purity and enabling efficient conversion to linear polarization.

Contribution

It presents experimental evidence that over 85% polarization purity can be preserved at 40dB amplification in fiber amplifiers for radial and azimuthal polarizations.

Findings

Over 85% polarization purity retained at 40dB amplification

Efficient conversion to linear polarization achieved

Fiber amplification preserves polarization states effectively

Abstract

The results on amplifying either radially or azimuthally polarized light with a fiber amplifier are presented. Experimental results reveal that more than 85% polarization purity can be retained at the output even with 40dB amplification, and that efficient conversion of the amplified light to linear polarization can be obtained.
