of an opticallyband-tunablecolorconelasingemission (CCLE) based on a dye-dopedcholestericliquidcrystal with a photoisomerizablechiraldopant. Experimental results indicate that the lasing band of the formed CCLE can be tuned optically among various color regions by adjusting the UV irradiated fluence. The optical band tunability of the laser is attributed to the presence of two chiral agents
