Figure 5

Chromaticity diagram. Chromaticity coordinate variation of the upconversion supercontinuum with respect to the central wavelength of near-IR pump laser with (a) extraordinary light and (b) ordinary light polarization states, respectively. The white emission colour is marked as the blue pentagram with its CIE coordinate.
