Study of laser actions by bird’s feathers with photonic crystals

Abstract Random lasers had been made by some biomaterials as light scattering materials, but natural photonic crystals have rarely reported materials. Here we demonstrate the ability of to drive laser actions sandwiched feathers Turquoise-Fronted Amazon parrot and dye between two plastic films. Parrot comprise abundant crystals, different color compose ratios crystal, which directly affect feather reflectance. In this study, multi-reflection that occurred at interface crystal gain media efficiently reduce threshold; therefore, more constitutes in feathers; lower threshold can be obtained. The random easily integration bird with a simple sustainable manufacturing approach.
