PTPO thin films have shown efficient nonreciprocal CP properties both in absorption and emission. The aim was to investigate whether the film's enhanced asymmetric absorption of RCP and LCP light could lead to the generation of CP laser emission. In our experiments, we achieved a DOCP of up to 0.6-substantially higher than previously reported for organic CP lasers. This result not only demonstrates the ability of self-assembled chiral films to overcome the limitations of traditional chiral media but also provides a novel approach for generating strong CP emission through cavity engineering. Our findings open new avenues for advanced photonic devices and offer deeper insights into chiral light-matter interactions in stimulated emission processes.
