A continuous-wave fiber laser characterization based on a Findlay–Clay analysis is proposed. With this procedure, commonly used for solid-state lasers, information about saturation power and reabsorption loss is obtained. The knowledge of these parameters is commonly sufficient for a number of fiber oscillator design issues, but it also allows estimating values for fabrication dependent parameters, such as absorption and emission cross-sections, doping concentrations and dopant effective diffusion areas. As an application example, a single-mode low-power oscillator employing standard and well-known fiber components has been studied, providing values in good agreement with previously reported spectroscopical measurements.

Abstract
A continuous-wave fiber laser characterization based on a Findlay–Clay analysis is proposed. With this procedure, commonly used for solid-state lasers, information about saturation power and reabsorption loss is obtained. The knowledge of these parameters is commonly sufficient for a number of fiber oscillator design issues, but it also allows estimating values for fabrication dependent parameters, such as absorption and emission cross-sections, doping concentrations and dopant effective diffusion areas. As an application example, a single-mode low-power oscillator employing standard and well-known fiber components has been studied, providing values in good agreement with previously reported spectroscopical measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
