This textbook discusses the basic principles and some applications of a rapidly developing branch，nonlinear optics(NLO)，in the optics science．Nonlinear optics emerged in 1961 and has got well matured in past forty years．As the volume of this textbook is limited，we will only talk about the most important principles and developments in nonlinear optics． Chapter 1 is the introduction to the graduates about the forty years development of nonlinear optics．Chapter 2 relates to the basic theory of the nonlinear optical susceptibility．Chapters 3 and 4 deal with the second—order nonlinear optical phenomena．Chapter 5 is an overviewof the third—order NLO effects．From Chapter 6 to chapter 10，four- wave mixing，stimulated scattering，resonant interaction，optical fiber the ultrashort lasers and ultrafast processes are discussed in order． For the real teaching program．more materials should be added．This textbook can act as a general description of nonlinear optics for people who are interesting in this branch．
