利用全息激发的方法，在染料掺杂的双折射液晶波导中实现了光泵分布反馈激光。利用具有低折射率的非线性液晶，实现了激光作用的单模运转。在外加电场的作用下，由于NLC分子的重新取向引起的NLC芯层有效折射率的变化，实现了单模激光波长的连续调谐。
Optically pumped distributed feedback (DFB) lasing has been demonstrated in a dye-doped nematic liquid-crystal (NLC) waveguide by holographic excitation. Utilizing NLC with a low refractive index, the single-mode operation of a laser action was realized. With an applied electric field, continuous tuning of the single-mode lasing wavelength was realized due to the change in the effective refractive index of the NLC core layer caused by the reorientation of NLC molecules.
