We present a plasma mirror configuration that im-proves the temporal pulse contrast of femtosecond terawatt laser pulses by a factor of thousand using a single antire-flection coated glass target. The device provides ultra-high contrast for experiments with a maximum repetition rate of 10 Hz. A third-order cross-correlator has been used to mea-sure the temporal pulse contrast for several different plasma mirror targets. It is shown that the ASE can be suppressed to a level of 10 −11 . A comparison between a triggered and an untriggered plasma mirror reveals differences in the inten-sity distribution of the focused beam. The triggered plasma mirror produces a slightly larger focus due to the expansion of the triggered plasma mirror at −3 ps before the main pulse. We propose a cost-effective AR-coated and a blank glass target to reduce the costs of the consumable target ma-terial. High-harmonic radiation on solid surfaces has been generated with different plasma mirror targets to demon-strate the high laser contrast.
