Overview and future prospects of laser plasma propulsion technology

Due to its high cost, low efficiency, complex operation and unsatisfactory recycling, traditional rocket propulsion by chemical fuels has hindered the exploration of outer space to further limits. With the rapid development of laser and space technology, the new technology of laser propulsion exhibits unique advantages and prospects. The mechanism and current development of laser plasma propulsion are reviwed, with mention of the technical problems and focus issues of laser plasma in micro－flight propulsion.
