虽然红宝石激光器已被用于研究无机晶体中的双光子过程、吸收和荧光，但迄今还没有报道过有机分子宽带光谱中的双光子过程的例子。我们用红宝石激光6943K谱线观察了多环芳烃分子晶体中的双光子激发。
Although ruby lasers''have been used for study-ing two-photon processes, absorption, and fluores-cence in inorganic crystals, 4 no examples of two-photon processes in the broad band spectra of or-ganic molecules have as yet been reported. We have detected two-photon excitation in a number of polycyclic aromatic molecular crystals from the 6943K line of a, ruby laser by observing the re-
