High-power lasers can produce high-velocity plasma flows moving at over 1000 km/s, speeds that are comparable to those of Supernova remnants and astrophysical jets. In laser-produced counter-streaming plasmas, it is possible to produce collisionless plasmas with high plasma densities of 1018–1019 cm−3 and with high flow velocity of ∼1000 km/s. We have performed experiments to create collisionless counter-streaming plasma flows using high-power laser systems。
