Frequency-angular distribution for terahertz emission of single-color laser filament plasma under electrostatic field
L. Seleznev, G. Rizaev, D. Pushkarev +7
Frequency-angular distributions for THz emission in the range of 0.1 - 3 THz generated in a single-color laser filament plasma situated both under and without electrostatic field a…
Similar angular THz radiation pattern emitted by filament plasma channel with different length
Andrey V. Koribut, Georgy E. Rizaev, Daria V. Mokrousova +5
Influence of plasma channel length on angular THz radiation pattern is studied experimentally. It is shown that the angular distribution of THz radiation depends only on the focusi…
Influence of dispersion stretching of ultrashort UV laser pulse on the critical power of self-focusing
A. A. Ionin, D. V. Mokrousova, D. A. Piterimov +3
The critical power of self-focusing in the air for ultrashort UV laser pulses stretched due to dispersion from 90 up to 730 fs was experimentally measured. It was shown that the pu…
