3C11 コレステリック液晶におけるレーザー発振の温度依存性及び電界効果(フォトニクス・光デバイス)

抄録

The laser action in a dye-doped cholesteric liquid crystal (CLC) has been investigated as a function of the temperature. The discontinuous shift of the lasing wavelength has been observed. It has been also found that the shift of the stop band in the CLC is also discontinuous when the size of the measured area for the spectrum is small. These results have been interpreted to originate from the disappearance of every a half period of the CLC helix in the unwinding process as the temperature decreases.
