Decade spanning radiofrequency emission from ultrashort laser generated plasma
The unique electron distribution, timescales and geometry of ultrashort pulse laser generated plasmas are a novel source of radio-frequency electromagnetic emission, with a bandwidth larger than 70 GHz. To identify the emission mechanism, we characterize the RF signal for a wide variety of experimental conditions.
