Abstract

This study investigates a spatially band-tunable color-cone lasing emission (CCLE) based on a dye-doped cholesteric liquid crystal with a photoisomerizable chiral dopant (IBM). Experimental results show that the lasing band of the formed CCLE of the cell with a photoinduced pitch gradient can be spatially tuned among various color regions by adjusting the pumped position of the cell. The spatially band tunability of the laser results from the UV-irradiation-induced decrease of the helical twisting power of IBM via transcis isomerization, accordingly shrinking the pitch of the cholesteric-liquid-crystal host. The total spatially tunable wavelength range for the laser exceeds 100nm.
