huotodakuningu suppression treatment manner of the Yb addition optical fiber, being huotodakuningu suppression treatment manner of the huotodakuningu suppression Yb

摘要

The huotodakuningu control processing method of relating to this invention prepared the Yb addition optical fiber where Yb is added to the core, in the said Yb addition optical fiber, that laser oscillation time the said optical fiber the 1st process which at least irradiates either gamma-ray, the x-ray or the electronic beams under the conditions for granting the energy which is higher than the light which is spread and, measured the loss spectrum of the infrared territory of the said optical fiber after the 1st process, selected the 2nd process which selects the optical fiber where loss of specific wave length has gone into the specified range and, in 2nd processProcessing the optical fiber, in the atmosphere which includes hydrogen it includes with the 3rd process which obtains the huotodakuningu control Yb addition optical fiber.
