NEW METHOD OF MAGNETIC-FIELD AND CURRENT GENERATION OUTSIDE LASER-PLASMA

A new mechanism of laser plasma generation of current along an irradia ted conductive target, and a considerable (more than 1000 times) enhan cement of magnetic field outside the plasma has been found. This mecha nism is realized in experimental configurations with spatial asymmetri es of target dimension scale. Such asymmetries with the largest possib le scale was found to be the main factor that determines electromagnet ic phenomena detected by external probes outside the laser plasma.
