Impact of Polarization on Mid-IR Air Filaments
Valentina Shumakova,Claudia Gollner,Andrius Baltuška,V. Yu. Fedorov,Stylianos Tzortzakis,A. A. Voronin,Aleksandr V. Mitrofanov,A. M. Zheltikov,Daniil Kartashov,Audrius Pugzlys +9 more
TL;DR: In this article, the authors report results of experimental investigation on polarization evolution and losses in linearly and circularly polarized mid-IR filaments in air under different focusing conditions, and show that the polarization evolution is not linear.
