Nonlinear optical properties of stimulated Brillouin scattering (SBS) to signal detection in water are analyzed. With the threshold characteristics, SBS only occurs when the high power laser is focused in the SBS cell. When there is an object present in front of the focus, it leads to lower incident intensity and then SBS does not occur. The backward SBS signal depends on the focusing location. The nonlinear optical properties of SBS process in the focusing regime are analyzed theoretically. Wit

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 nanosecond (1064 nm, 10 ns, 10 Hz) CVBs have been directly produced with mode conversion efficiency of ～18 dB (98.4%) via an acoustically ind

Neutron stimulated emission computed tomography (NSECT) is a new approach for biological spectroscopy and imaging. Since thegamma-ray photons emitted from stimulated element have energies from 100 keV to about 6 MeV, previous reports have proposed thatthe projection path can be defined by the neutron beam. In this paper, another possible method has been applied and the performancepresented through simulations. When using signals from a single BGO crystal it is impossible to achieve g
