We demonstrate a laser-diode (LD) pumped actively Q-switched laser with Nd:Sc0.2Y0.8SiO5(Nd:SYSO) crystal for the first time. A stable actively Q-switched laser is obtained at dual wavelengths of 1 075.2 nm and 1 078.2 nm.
Based on the inverse Faraday effect, a super-long longitudinal magnetization needle can be induced by a transversely polarized needle-shaped electric field. This needle-shaped electric field can be obtained in the focal volume of the objective by focusing
We report the “periodic” soliton explosions induced by intracavity soliton collisions in a dual-wavelength mode-locked Yb-doped fiber laser. Owing to the different group velocities of the two wavelengths, the mode-locked solitons centered at different wav
In this study, a novel photosensitizer meso-tetra (3-pyrrolidinomethyl-4-methoxyphenyl) chlorin (TPMC) was reported. It displays a characteristic long wavelength absorption peak at 656 nm and it shows a singlet oxygen quantum yield of 0.48. After light ir
