Light-driven inching random laser
Abstract
We present a light-driven inching random laser composed of a liquid crystal elastomer body and a random lasing tip region. Under optical illumination, the composite random laser undergoes bending deformation, enabling a remote-controlled motion on flat and blazed grating surfaces. The inching random laser is optically guided to a designated target position, where the integrated random-lasing tip generates emission characterized by a bandwidth collapse and a distinct lasing threshold. The light-driven inching random laser offers a promising platform for delivering intense optical signals at a desired location.
