Abstract
We report a large jetlike collimated emission feature from colliding laser-produced plasmas (LPPs). The plasmas are produced by focusing two parallel laser beams on a planar copper target. Time-resolved spectrally integrated emission features in the visible region are recorded using an intensified charge-coupled device camera. Both laser plasmas expanded perpendicular to the target and collided side-on. The jetlike emission has a spatial extension of more than 3 cm and exists in a prolonged time compared with single LPPs.
