Paper Abstract

Fast photography is used to investigate expansion dynamics of colliding laser produced magnesium plasmas. A ruby laser pulse is split into two beams by the help of a movable glass wedge and focused onto two magnesium targets placed at 90 degrees to each other. The intensity ratio of the two laser beams is 7:1 that created hot and cold plasmas on the target surfaces. A collision region is observed 6 ns after the laser maximum and its emission is found to increase with time.
