Multi-purpose Optical Micro-manipulation Platform and Applications
[in Chinese], and [in Chinese]
Optical micro-manipulation platform is a new type of micro-control, micro-fabrication and micro-measuring system, which combines the capabilities of optical tweezers, femtosecond laser scissors and microspectrometer. Different from conventional micro-mechanical system, the optical micro-manipulation system can tweeze, Optical micro-manipulation platform is a new type of micro-control, micro-fabrication and micro-measuring system, which combines the capabilities of optical tweezers, femtosecond laser scissors and microspectrometer. Different from conventional micro-mechanical system, the optical micro-manipulation system can tweeze, manipulate and fabricate small "work pieces" such as biological cells, organelles and other micro-particles by light. It is a remote micro-process without any mechanical touch. The optical micro-manipulation platform has the advantages of in vivo, non-invasive, nonphysical damage, remote-control, and can be used in many precise operations such as cells sorting, cells amalgamation, chromosome incision, DNA transplant, micro-surgery, molecular motors and spectral measurement of micro-sized samples. It can be widely used in the fields of biology, chemistry, material science and nano-science..

New Development of Nonlinearity Management in High Power Fiber Lasers and Amplifiers
[in Chinese], and [in Chinese]
The scalability of output power and transmission characteristic of high power fiber lasers and amplifiers are limited by nonlinear effects such as stimulated Brillouin scattering, stimulated Raman scattering and self-phase modulation. These limitations can be overcome through improving the fiber in geometric structure The scalability of output power and transmission characteristic of high power fiber lasers and amplifiers are limited by nonlinear effects such as stimulated Brillouin scattering, stimulated Raman scattering and self-phase modulation. These limitations can be overcome through improving the fiber in geometric structure or compositional distribution, doped technology, working conditions etc. This paper firstly discusses the mechanism of production and the properties of power threshold about nonlinear effects of fiber lasers and amplifiers. Then it emphasizes particularly on the new methods and technologies used in nonlinearity management. The new managing way like large-mode-area fiber designing as well as varying doped componments and distribution，direct nanoparticle deposition doping and controlling strain or temperature effects is introduced in detail. Finally, it presents reasonable schemes..
