摘要： The method for producing and processing a preform (1p, 1s) comprises a preliminary process phase, in which silica grain (5a; 5b) is supplied into the interior space (110) of a silica tube (11) having an open upper end and a closed lower end (111), in order to obtain an unprocessed preform (1p, 1s ), and comprises a final process phase, in which the interior space (110) of the silica tube (11) is closed, a condition of reduced pressure is generated, the unprocessed preform (1p, 1s ) is heated with a final process temperature in order to fuse the silica tube (11) and the silica grain (5b). According to the invention the silica grain (5a; 5b) entering the interior space (110) is thermally treated during the preliminary process phase with an intermediate process temperature that lies under the melting point of the silica grain.

摘要： The present invention relates to a method and an apparatus for fabricating a primary, secondary or higher order preform (1, 10, 100) that can be used for drawing an active optical fiber (8). The present invention further relates to an active optical fiber (8), designed for amplification or attenuation purposes, drawn from said preform (1, 10, 100) and to an optical amplifier (600, 601) using a laser active optical fiber. With the inventive method, preforms (1, 10, 100) can be produced with primary and silica tubes (11; 11d; 111), which limit an interior or outer space that can be filled with primary or secondary silica grain (51, 510). In order to achieve activity, particularly laser activity of the fiber (8) subsequently drawn from the preform (1, 10, 100), at least one of the silica tubes and/or the primary or secondary silica grain (51, 510) are doped with A/A-material (520) of at least one sort. After the assembly the preform (10, 100) of secondary or ternary order, which already contains at least one preferably inventive processed or unprocessed primary preform, then the secondary or ternary preform (10, 100) is heated in order to obtain a final preform from which the active optical fiber (8) can be drawn simultaneously or in an a subsequent process step. An inventive active optical fiber (8) can be used in an attenuator or in an optical amplifier (600, 601), which comprises a source unit (62) from which a pump signal can be delivered to the active zone of the inventive optical fiber (8).
