Our work introduces a novel approach to generating CP light by incorporating a unique chiral organic thin film with nonreciprocal CD properties. This nonreciprocal behavior, known as apparent circular dichroism (ACD), originates from the material's 2D chirality of oriented molecules, which results in directional-dependent CD. The film displays nearly opposite CD responses when illuminated from its front and back surfaces, leading to an accumulated asymmetry in the absorption of RCP and LCP light over multiple passes within the cavity. This induced asymmetry in cavity loss has the potential to significantly enhance the degree of circular polarization (DOCP) in the laser output.
