Controllable ultrabroadband supercontinuum during twocolor femtosecond laser filamentation in high pressure gases
Yury E. Geints, Victor O. Kompanets, Sergey V. Chekalin
Twocolor laser filamentation is considered a promising strategy for deep transformations of the spectrum and generating ultrashort light pulses, which is critically important for d…
