Professor Ruan Shuangchen from Shenzhen University School of Optoelectronic Engineering made significant progress in Raman nano laser research. The research report "A Thresholdless Tunable Raman Nanolaser using a ZnO Graphene Superlattice" is published in Advanced Materials. With the development of nano-optical technologies such as chip-level optical communication and biomedical imaging, research into lasers has entered the sub-wavelength range. The development of subwavelength lasers, such as nano-laser, is mainly based on the surface plasmon-enhanced emission technique. However, the general fixed wavelength of the nano-laser limits its application, and the Raman scattering can change the pump light to a new wavelength. The development of a new type of Raman nano-laser can obtain the tunable wavelength of the nano-laser and it is possible to obtain the application Innovative breakthroughs. Professor Ruan Shuangchen team synthesized a new type of graphene-based superlattice material by space-limited growth method. The graphene-based superlattice can excite surface plasmon in a wide wavelength range of visible to near-infrared, The superlattice material can obtain tunable Raman nanometer laser. The Raman nano laser has the advantages of no threshold, operation at room temperature, adjustable laser wavelength and wide range of laser wavelength - from the visible light to the near infrared light band and so on, promising to be applied in nano-light technology such as biomedical imaging New Breakthrough The research was funded by the National Natural Science Foundation of China and the Foundation for Basic Research of Shenzhen Branch of Science and Technology. barbed wire,Barebed Wire,Stainless Steel Wire Hogs Fence,Iron Wire Barbed Wire anping yaqi wire mesh co.,ltd , https://www.apyaqiwiremesh.com
