title: Robust integrated optofluidic-ring-resonator dye lasers.
abstract: We demonstrate a robust optofluidic dye laser that integrates fluidics with a high Q-factor ring resonator. In this optofluidic laser the ring resonator is formed by an optical fiber fused on the inner surface of a glass capillary serving as a fluidic channel. Laser oscillation is achieved with a threshold of 7 microJ/mm2 per pulse. Furthermore, the laser emission can be directionally outcoupled through a fiber prism for easy and efficient light delivery.
