Abstract
The invention provides a continuous-wave pumped polymer laser and preparation method thereof, comprising: coating an organic polymer solution onto a substrate to form an polymer film, and applying a template having a distributed feedback structure to the polymer film, or coating an organic polymer solution onto a substrate having a distributed feedback structure to form an polymer film, and applying a plate to the polymer film; heating the substrate to reach above the phase transition temperature of the organic polymer, and applying a pressure to the template or plate for 1-100 min; and cooling the substrate to reach below the phase transition temperature of the organic polymer, and removing the template or plate from the organic polymer. The method of the invention is simple, the organic polymer molecular chain and supramolecular structure are oriented to have long range order, and the obtained laser can use continuous-wave pumping.
