We proposed a method to form a flat transmitted serrated-phase(SP)high-contrast-index subwavelength gra-ting(HCG)beam splitter(HBS)for all dielectric materials,
A continuous-wave Nd:YVO4/BaWO4 Raman laser generating simultaneous multi-wavelength first-Stokes and second-Stokes emissions is demonstrated for the first time
This Letter presents a new type of optical fiber probe used to detect temperature,whose structure is very simple.The optical fiber probe is filled with choleste
