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. This work is supported by the Office of Naval Research.

N2 - We present first evidence of backwards lasing from Krypton present in atmospheric air. Two-photon femtosecond UV excitation leads to stimulated emission at 759nm. The air laser can be used for standoff detection.
