Optofluidic random laser

Abstract

An active disordered medium able to lase is called a random laser (RL). We demonstrate random lasing due to inherent disorder in a dye circulated structured microfluidic channel. We consistently observe RL modes which are varied by changing the pumping conditions. Potential applications for on-chip sources and sensors are discussed.
