Rainbow from nowhere (Conference Presentation)

Paper Abstract

Filamentation in air is a profound effect caused by high energy photons. While it has been studied in a wide-range of laser systems, there still exist wavelength regimes where filamentation hasn’t been created, due to lack of sources. Using a tunable near-infrared femtosecond laser, we generated filamentation in air by wavelengths from 1.2 to 2.5 µm. The observed filaments produced harmonic and continuum generation well into the visible spectrum; a rainbow of colors.
