We present the generation of the nanosecond cylindrical vector beams(CVBs)in a two-mode fiber(TMF)and its applications of stimulated Raman scattering.The nanose
We propose a concept of wavelength synchronization to ensure the stability of ultra-dense channels in an ultra-dense wavelength division multiplexing passive op
An enhancement method of rapid lifetime determination is proposed for time-resolved fluorescence imaging to discrimi-nate substances with approximate fluorescen
