An investigation of self-focussing of a laser pulse in a laser-produced plasma
We have investigated self-focussing of a laser beam in a laser-produced plasma, exploring the possibility of using the phenomenon as a technique to generate very high laser flux densities within a plasma. Using a modified version of Siegrist's TRSF computer program we have studied the variation of the self-focussing threshold as a function of several laser and plasma parameters particularly those affecting the peak intensity achievable in the self-focussing filament, namely, laser pulse...[Show more]
