Abstract: The basic concept and realization thought of laser comprehensive applications are introduced in order to improve the overall performance and optimize the design of weapon platforms.Laser comprehensive application systems are classifed into 3 types according to different lasers used.The first type is pulse solidstate lasers with peak power of MW to hundreds MW.The prototype with 2 J pulse energy has been developed.The second type is high frequency lasers with peak power of hundreds W to thousands W.The third type is pulse semiconductor lasers with average power of mW to W.These 3 multifunction laser comprehensive application systems will play an important role in future new weapon platforms,and it will necessarily promote the total performance of series of future new weapon platforms tremendously.
