Abstract
We present what to our knowledge is the first time-resolved measuremen t of the electron density profile of a laser-driven concentric implosi on; Cylindrically symmetric plasmas are driven by two spatially coinci dent line-focused laser pulses. If a plasma channel is allowed to form after the first pulse, the second pulse drives an inward compression wave which converges on the channel axis and later relaxes. The two-pu lse absorption and ionization can significantly exceed that due to a s ingle pulse of the same total energy, with the second pulse being almo st totally absorbed.
