The system has a passive control unit for controlling variations of optical power of the system according to temperature. The control unit includes a pump diode whose wavelength is approximately distinct from an absorption peak of a doped fiber of the system, where the wavelength ranges between 920 and 940 Newton m at 25 degrees Celsius, and operating current of the diode is distinct when the doped fiber is a doped erbium/ytterbium fiber. The control unit includes two pump lasers having distinct wavelength and maximum pumping efficiency for different temperatures. |
