Light sources are used in optofluidic devices for real-time system control and quantitative analysis of important process parameters. In this work, we present a random laser source using hollow-core antiresonant reflecting optical waveguide (HC-ARROW) containing the gain media inside reservoir to reduce dye bleaching, which is connected microchannel waveguides increase beam directionality. The device pumped externally emits highly coherent collimated beam.
