Abstract

An amplified cholesteric liquid crystal (CLC) laser performance is demonstrated by utilizing a binary-dye mixture (with 62 wt% DCM and 38 wt% PM597) as the active medium and an external stable resonator. The measured results show that the laser efficiency is enhanced as compared to the highest efficiency of each individual dye. Furthermore, using such an active CLC in an external stable resonator leads to a approximately 92X improved efficiency over the single CLC laser. In this instance, the binary-dye doped CLC simultaneously functions as laser oscillator and amplifier.

摘要

通过使用二元染料混合物（62重量％的二氯甲烷和38重量％的PM597）作为活性介质和外部稳定谐振器，展示了一种放大的胆甾相液晶（CLC）激光性能。测量结果表明，与每种单独染料的最高效率相比，激光效率得到了提高。此外，在外部稳定谐振器中使用这种活性CLC，与单CLC激光器相比，效率提高了约92倍。在这种情况下，二元染料掺杂的CLC同时起到激光振荡器和放大器的作用。
