We demonstrate a compact hybrid structure red-green-ultraviolet three-color laser consisting of three distinct semiconductor nanowires (CdSe, CdS and ZnO) attached to silica microfiber, which is pumped by 355 nm wavelength pulses. The exciting the collection photoluminescence (PL) are implemented means evanescent coupling through same microfiber. When pump energy higher than 1.3 microJ, spatially spectrally lasing groups can be measured at output port simultaneously. approach extended other materials produce lasers that cover ultraviolet near infrared spectral regions.
