摘要：

We use simulations to investigate the interaction of ultra-intense laser pulses with a plasma. With an intensity greater than 10(18) W/cm2, these pulses have a pressure greater than 10(3) Mbar and drive the plasma relativistically. Hole boring by the light beam is a key feature of the interaction. We find substantial absorption into heated electrons with a characteristic temperature of order the ponderomotive potential. Other effects include a dependence on the polarization of the incident light, strong magnetic field generation, and a period of intense instability generation in the underdense plasma.
