Abstract: Laser propulsion(LP) is perhaps one of the most realistic advanced propulsion concepts and an effective alternative to conventional rocket launching techniques.A laser is used in laser propulsion as a remote energy source for propulsion.The thrust is produced by high energy exhaust stream caused by laser-induced vaporization of material.More and more scholars have been showing a great interest in laser propulsion for its high specific impulse,low cost,high reliability,etc.The studies on laser propulsion have been carried out in USA,Japan,Germany,Russia,etc.Laser propulsion has a wide application in the field of micro-satellite launch into LEO,attitude and orbit control,and etc.The study programs of laser propulsion in recent years have been summarized with the discussions of its future development trend.This review may provide a guide for further study of laser propulsion.
