Título: | Portable IR dye laser optofluidic microresonator as a temperature and chemical sensor |
Autor: | Lahoz, F.; Martín, I. R.; Gil-Rostra, J. CSIC ORCID; Oliva-Ramírez, Manuel CSIC ORCID ; Yubero, Francisco CSIC ORCID; González-Elipe, Agustín R. CSIC ORCID | Fecha de publicación: | 2016 | Editor: | Optical Society of America | Citación: | Optics Express, 24(13): 14383-14392 (2016) | Resumen: | A compact and portable optofluidic microresonator has been fabricated and characterized. It is based on a Fabry-Perot microcavity consisting essentially of two tailored dichroic Bragg mirrors prepared by reactive magnetron sputtering deposition. The microresonator has been filled with an ethanol solution of Nile-Blue dye. Infrared laser emission has been measured with a pump threshold as low as 0.12 MW/cm<sup>2</sup> and an external energy conversion efficiency of 41%. The application of the device as a temperature and a chemical sensor is demonstrated. Small temperature variations as well as small amount of water concentrations in the liquid laser medium are detected as a shift of the resonant laser modes. | Versión del editor: | http://dx.doi.org/10.1364/OE.24.014383. | URI: | http://hdl.handle.net/10261/136945 | DOI: | 10.1364/OE.24.014383 |
