Laser transfer in plasma produced by CH foam

This paper reports the laser transfer in plasma produced by CH on Shengguang Ⅱ. The laser transmission rate was decided by the plasma density. When the laser incidence was 0.5 μm CH on Shengguang Ⅱ, the plasma density would be under critical value after 200 ps, the laser would pass the plasma. When the plasma density was 1% critical density after 700 ps, the laser could pass the plasma completely. (authors)
