| Abstract [eng] |
Tunable mid-infrared radiation in the range of 2.06– $$12\,\mu $$ m was generated in air via loosely focused two-color femtosecond laser pulses. The emission spectra and beam profiles confirm its origin as four-wave difference-frequency mixing in a low-density air plasma filament. Near phase-matching due to low air dispersion opens possibilities for efficient energy conversion at high powers. |
