Optically pumped lasing of epitaxially oriented molecular crystals is presented. Needle-like crystals of a thiophene/phenylene co-oligomer is grown along the [110] direction of a KCl substrate. The fluorescence light is one-dimensionally confined and amplified by the self-waveguiding effect in the elongated needles. The Fabry-Pérot resonation by the terminated ends results in laser oscillations corresponding to the needle length.
本文介绍了外延取向分子晶体的光泵激光。噻吩/亚苯基共低聚物的针状晶体沿 KCl 衬底的[110]方向生长。荧光光通过在细长针中的自波导效应被一维限制和放大。由于末端的法布里-珀罗共振，导致激光振荡与针的长度相对应。
