Abstract
We have successfully designed, fabricated and charac- terized a micro-cavity fluidic dye laser with metallic mirrors, which can be integrated with polymer based lab-on-a-chip microsystems without further processing steps. A simple rate-equation model is used to predict the average pumping power threshold for lasing as func- tion of cavity-mirror reflectance, laser dye concentration and cavity length. The laser device is characterized us- ing the laser dye Rhodamine 6G dissolved in ethanol. Lasing is observed, and the influence of dye concentra- tion is investigated.Keywords
