New Technology and New Configuration for High Energy Laser System

Several key techniques used in the high energy laser system nowadays, such as adaptive optics, beam control, have been challenged on the way from laboratory to practical application. We investigate several new techniques proposed recently, which can solve those problems in some degree. Then a new configuration for high energy laser system, APPLE(Adaptive Photonic Phase-Locked Elements), is introduced, which will realize the integration of those new techniques and have a great potential for different applications. The technical challenges for APPLE are discussed.
