Full-color WGM lasing in fiber braiding cavity

Caption

(a) The PL spectra for seven combinations lasing. The numbers show the CIE1931 coordinates calculated from the corresponding spectra. From bottom to top: B-, G-, R-, G+B-, R+B-, R+G- and R+G+B-emitting lasing fibers. (b) Chromaticity diagram of lasing peaks (a) with white circles. The dashed and solid lines show the range of the achievable color gamut for the RGB fiber braiding cavity and standard RGB space, respectively.
