光泵浦有机薄膜激光器是通过堆叠顶部和底部布拉格反射器以及反射器之间的内腔有源层来制造的。我们通过将吡咯亚甲基-567 染料掺杂到所有堆叠层中，观察了 555 nm 的单纵模激光操作。该激光器的阈值比使用非掺杂布拉格反射器操作的激光器的阈值低 30%，这与计算结果非常吻合。
Optically pumped organic thin-film lasers were fabricated by stacking top and bottom Bragg reflectors with an inner-cavity active layer between the reflectors. We observed single-longitudinal-mode laser operation at 555 nm by doping pyrromethene-567 dye into all the stacked layers. The threshold of the laser was 30% less than that of a laser operated with nondoped Bragg reflectors, which was in good agreement with calculations.
