【Abstract】 Since optical pulse shaping technique plays a crucial role on the application of ultrashort pulse, its development is very fast.In this paper,the recent progresses on its theory and methods both in the domestic and overseas are introduced. In terms of methods,the main approaches of optical pulse shaping include the application of waveguide modulator and deflector, the nonlinear briefringent and filter of space.The 4F systems with various special modulators are presented in detail.Finally, the future trend of optical pulse shaping is discussed.更多还原
