Dr. Zhang is author or co-author of over 30 papers in peer-reviewed journals and international conference proceedings. Currently, he joins the Shanghai University, and his interests involve nonlinear fiber optics, optical fiber laser and optical fiber sensing.

报告摘要

Random fiber lasers (RFLs) has been widely demonstrated by incorporating one-dimensional random feedback of distributed Rayleigh scattering from refractive index inhomogeneity in silica fiber instead of conventional mirror. As a new breed of laser， coherent random fiber lasers with unique spectral dynamic and noise properties have shown immense potentials in underlying fundamental research as well as practical applications such as fiber optics communication and fiber sensing. In this talk, recent advances in improving the performance of coherent random fiber laser as well as its practical applications, such as optical metrology and optical fiber sensing, will be presented and discussed.
