"Defence Research & Development Canada-Valcartier (DRDC Valcartier) initiated many projects on femtosecond laser based counter-measure applications. One of the main properties of high peak power femtosecond laser pulses is their transformation into a white-light supercontinuum, which can be exploited for dazzle (and possibly damage) countermeasure purposes. Contrary to normal dazzle generated using a narrow-spectrum laser source, the white-light surpercontinuum from femtosecond laser pulses spans continuously from the ultraviolet up to the infrared. Such broadband white-light lasers are virtually impossible to block because they do not rely on a single wavelength to achieve the effect. This report presents the characterization of the white-light laser burst produced during the propagation in air of a femtosecond-Terawatt laser. The supercontinuum was generated from 200 nm in the ultraviolet up to 13.6 µm in the far infrared, which led to the first worldwide demonstration of such a broadband laser source"--Abstract, page i.
