Abstract : brief introduction to ( 2 ) cascading nonlinearities is presented . the enhancement mechanisms for optical kerr effect and the photorefractive effect as ( 2 ) cascading process are discussed . mutual inductance between quadric and cubic nonlinearities opens possibilities for engineering optical nonlinearities 文摘:介紹了( 2 )串級非線性.討論了串級光克爾非線性和串級光折變非線性的增強(qiáng)機(jī)制,并指出二階和三階非線性的相互轉(zhuǎn)化,為光學(xué)非線性工程設(shè)計(jì)提供了可行性
