英文摘要：

An extensive, review was presented on the progress of laser propulsion research during the past 40 years since the concept of laser propulsion was proposed. The three key components and the critical problems of laser propulsion research were discussed. The direction of future development of the laser propulsion technology was also analyzed The main performance parameters, the advantages compared to the conventional chemical propulsion, the commonly-used experimental methods, and the classification of laser propulsion were introduced in detail. The researches on the ultrashort pulse laser ablative propulsion done by our group during the recent years were summarized in the end, including the measurement of the ablation generated momentum by ultrashort laser pulses with different pulse energies, pulse widths and laser fluence by using a home-made torsion pendulum, and some demonstration experiments of propelling micro beads both in the horizontal and vertical directions by using focused ultrashort laser pulses.
