Abstract

A lateral pumped fiber structure comprises: at least one active optical fiber, which is used to generate laser or amplify the laser; at least one passive optical fiber, which is used to connect a pumping source. The active optical fiber and the passive optical fiber form an optical contact in a radial direction. The manufacturing method of the lateral pumped fiber structure comprises the following steps: 1) respectively preparing an active optical fiber performing rod and a passive optical fiber performing rod; 2) respectively performing wire drawing to the prepared active optical fiber performing rod and the passive optical fiber performing rod and making the active optical fiber and the passive optical fiber; 3) coupling at least one active optical fiber to at least one passive optical fiber so that the optical contact in a radial direction between the active optical fiber and the passive optical fiber can be formed. By using the fiber structure of the invention, pumping efficiency is high; a manufacturing technology and coupling equipment are simple; costs are low. The fiber structure of the invention is especially suitable for a high power optical fiber laser and an optical fiber amplifier.
