note = "Funding Information: In conclusion, we present for the first time evidence of backwards lasing in atmospheric air from direct two-photon excitation of Krypton atoms using a broadband commercial femtosecond laser. The backwards emission at 759nm is obtained from the 1ppm Kr naturally present in air, and we expect that this air lasing will be able to aid the efforts for standoff trace species detection.
