通过在有源电池中加入无源胆甾液晶反射器，研制了一种高性能染料掺杂胆甾液晶激光器。偏振保守的CLC反射器有效地增加了分布反馈腔的长度，从而显著提高了激光效率，并显著降低了光束发散。激光特性仍以圆偏振光为主，具有与胆甾螺旋相同的感觉。(c) 2006年美国光学学会。
A high performance dye-doped cholesteric liquid crystal (CLC) laser is demonstrated by incorporating a passive CLC reflector to the active cell. The polarization-conserved CLC reflector effectively increases the distributed feedback cavity length which, in turn, results in a significant enhancement in lasing efficiency and a dramatic reduction in beam divergence. The lasing characteristics are still dominated by the circularly polarized light with the same sense as the cholesteric helix. (c) 2006 Optical Society of America.
