Abstract

We have synthesized a luminescent dye that exhibits good solubility in cholesteric liquid crystals and broadband spectral emission. By incorporating this dye into cholesteric liquid crystal and using a nitrogen laser beam as the pumping source, a stable laser emission from the dye-doped cholesteric liquid crystal has been generated. We conducted a temperature-controlled tuning of the laser lines, achieving an extra-wide spectral range of over 172nm, which is the broadest spectral interval so far, using a single luminescent dye.
