【発明の名称】ドーピングした光ファイバを用いるレーザ増幅器
Document Type and Number:
Japanese Patent JP2742309
Kind Code:
B2
Abstract:
An erbium-doped fiber laser amplifier (1), characterized by the fact that said fiber (3) is doped to a concentration lying in the range 5 ppm to 50 ppm, that the length of said fiber lies in the range 250 m to 30 m depending on the selected concentration of doping, and that the radial position of the doped zone substantially coincides with the energy maximum of the set of propagation modes in said fiber at the pumping wavelength.
