Influence of the expansion velocity of laser plasma bunches on the intensity of a plasma jet and quasistationary waves generated in a magnetic tube.

The influence of the Alfven Mach number (MA) on the intensity and length of quasistationary Alfven (AQW) and slow magnetosonic (MQW) waves and plasma jets generated by periodic laser plasma bunches in a of magnetized plasma was studied. It was shown that the intensity and wavelength at low velocities of the plasma expansion are maximum, which correspond to MA ∼ 0.2 − 0.5. Waves and energy of pumping bunches contain more than 60% of energy of bunches. [ABSTRACT FROM AUTHOR]
