The plasmas generated in the laser interacting with targets can be used as a new propulsive source. In this paper, the effects of the target configuration on the laser plasma momentum-coupling coefficient are investigated. Results show that, compared with planar targets, the momentum-coupling coefficient is enhanced five times by the cavity target, and over ten times for the confined planar target. It is found that effectively confined plasma expansion is the main reason for the enhancement of the momentum-coupling coefficient.
