13‐1: <i>Invited Paper:</i> Organic Laser Indirectly Pumped by an Integrated OLED

Realizing direct electrical pumping of organic lasers remains a long‐standing challenge due to carriers and triplets preventing lasing by absorbing the emitted light and quenching singlets. Here, we address this grand challenge of organic optoelectronics by integrating a thin‐film polymer distributed feedback laser onto the substrate of a pulsed blue OLED with record‐high light output. The OLED optically excites the laser, inducing population inversion and enabling an electrically driven laser.
