Experimental dependences of the light yield of laser plasma … WebIn summary, the above analytical model provides basis for control of the filamentation range in the plasma burst application system by setting the divergence, beam diameter, power, pulse length, pulse shape and wavelength. The power of the laser beam eventually reduces to the Kerr threshold P N. That is, the sudden onset of multiphoton ...

In this paper, we carry out fully kinetic particle-in-cell simulations of the FI in unmagnetized pair plasmas.
WebPlasma defocusing is described by the plasma oscillation frequency, ( qe is the electron charge, me is the electron mass, and ρ is the free electron density). The last term in Equation (1) accounts for multiphoton absorption (MPA). The MPA term accounts for energy absorption due to multiphoton ionization [ 9 ].

The filaments, having made a plasma, turn the narrowband laser pulse into a broadband pulse having a wholly new set of applications. An interesting aspect of the filamentation induced plasma is the limited density of the electrons, a process which prevents the optical breakdown. This effect provides an excellent source for spectroscopy of high pressure with low level of continuum and also smaller line broadening. Another potential application is the LIDAR-monitori…
