Multi-wavelength lasing in a dye-doped cholesteric liquid crystal (CLC) cell is demonstrated. By adding oversaturated
chiral dopant, the multi-photonic band CLC structure can be obtained with non-uniform chiral solubility. Under
appropriate excitation, multi-wavelength lasing can be achieved with a multi-photonic band edge CLC structure. The
number of lasings can be controlled under various temperature processes. Nine wavelength CLC lasings were observed
simultaneously. The wavelength range covers around 600-675nm.
