Abstract :
We have studied optical guiding of high-intensity laser pulses using fast Z-pinch for channel guided laser wakefield acceleration (LWFA). A fast Z-pinch discharge can produce a long stable plasma channel which has a concave electron density profile in its core. We experimentally demonstrated the feasibility of optical guiding of high-intensity laser pulses (>1017 W/cm2) using Z-pinch discharge channel. A ray-trace calculation of the Ti:Sapphire laser pulse in the channel has been done, which could well explain the experimental results.
