Shanghai Institute of Optics and Engineering announced the nonlinear optical review of graphene and its derivatives

Optical limiting material, mechanism and development history

Recently, the research team of the Institute of Optics and Fine Mechanics, Shanghai Institute of Optics and Fine Mechanics, Wang Jun, and East China University of Science and Technology, Prof. Chen Hao, published a long review article by the author of the joint news report. Graphene and its derivatives for laser protection The journal "Progress in Materials Science" is accepted.

With the development of laser technology, laser radiation poses an increasingly serious threat to human eyes, conventional instrument optical windows, and photodetectors. The development of an effective laser protector can protect human eyes and optical and photoelectric sensors from laser beam damage. . As the first experimentally validated two-dimensional nanomaterial, graphene, with its unique structure and physicochemical properties, set off a wave of nanoscale research. It is considered to be an ideal material for modern photonics and optoelectronic devices. Limiter is an important application. This review paper firstly introduced the mechanism of graphene and its derivatives and the effect of laser protection on optical limiting effect. It also introduced in detail the research progress of nonlinear optical and optical limiting materials based on graphene and its derivatives in the world, and it needs to be solved urgently. The main issues and future development directions provide guidance for the development of laser protection devices based on graphene and its diffraction products.
