The Application Of Near-field Optics In Laser

The era today is information era.The nanophotonics will exert a world of use under this situation.First the paper introduce the latest development in the nanophotonics,and introduces experiments on it conducted by many research groups,including nanophotonic switch,optical near-field probe,the nanometer-scale energy transition terminal between optical far field and near field carried out by plasmon wave guide.Then this paper introduced the technic theory of laser particularly,and its application in every ways of socialty.The LASER is a high-tech equipment appeared in 1960 .It possesses many uses in physic and military.In modern technology,the LASER developed very quickly,all kinds of high-powered new LASER appear ceaselessly.The near-field optics that this paper introduces is unlikeness with traditional optics.The electromagnetism character of near-field optics that bases on one wavelength distance.It measure and work in nano-meter scale.After this paper links qualities of near-field optics and LASER,it introduces some relationship that exists. Such as when the LASER is in the near-field area,the measurement of some useful information.It will use the SNOM,when the near-field come into being,the electromagnetism field.It will appear only when some moment of...
