| 主权项 | 1. A light output control apparatus, comprising: an excitation light source that outputs excitation light; an excitation light guiding unit that guides the excitation light to an optical amplifying medium for transmitting a signal light; and a loss causing unit that includes an optical transmission medium located between the excitation light source and the excitation light guiding unit, and changes a radius of curvature of the optical transmission medium so that the loss causing unit outputs the excitation light whose control value is less than a lower limit value of the excitation light source. | ||
