Flexible polymer laser devices excited by low‐threshold optical light are fabricated from colloidal crystals (CCs; see figure). The laser‐cavity structure consists of a light‐emitting layer sandwiched between two polymer CC films. Optical excitation with a green beam brings about emission with a red beam. This process allows the production of ultralightweight, low‐cost, flexible, and easily processible all‐plastic lasers.
