Reportamos una solución técnica simple para un ajuste preciso de la longitud de cavidades cortas de fibra óptica usadas comúnmente en los láseres de Brillouin. La cavidad ajustada del láser es simultáneamente resonante para el bombeo y la emisión de Stokes. La técnica propuesta está basada en registrar la respuesta de Brillouin de la cavidad a un escaneo frecuencial de la emisión del láser de bombeo. Las trazas almacenadas son utilizadas para calcular el exceso de longitud de la cavidad que necesita ser removido de la cavidad original para un ajuste preciso de la resonancia de Brillouin en cualquier longitud de onda preseleccionada del láser de bombeo. Para la comprobación de su funcionamiento se desarrolló el ajuste fino de una cavidad de anillo basada en fibra estándar SMF-28 de Corning de 4 m de longitud. Además, se presenta un análisis detallado del error en el algoritmo de ajuste de la doble resonancia en la cavidad de anillo de fibra del láser de Brillouin de corta longitud. La propuesta presentada es igual de útil para el diseño de láseres de fibra monomodo de espectro óptico ultra-angosto y láseres de fibra de Brillouin Q-switched, así como para aplicaciones que emplean alta potencia en cavidades de fibra que evitan la dispersión de Brillouin estimulada.
We report a simple technical solution for precise adjustment of short fiber cavities commonly used with Brillouin fiber lasers. The adjusted laser cavity is simultaneously resonant for pump and Stokes radiations. The technique is based on recording the Brillouin response of the cavity to the frequency scanned laser radiation. The recorded traces are used to calculate the excess cavity length that needs to be removed from the original cavity to provide its precise adjustment to the Brillouin resonance at any preselected pump laser wavelength. For demonstration of the approach, fine adjustment of a 4 m long ring cavity based on standard Corning SMF-28 fiber is performed. A detailed error analysis of the algorithm for adjustment of double resonance in short-length Brillouin ring fiber laser was presented. Demonstrated approach is equally useful for the design of single mode fiber lasers with ultra-narrow optical spectra, Q-switched Brillouin fiber lasers as well as for applications employing high power fiber cavities free from stimulated Brillouin scattering.
