摘要： Apparatus for laser processing a material (8) with optical radiation (T), which apparatus comprises a seed laser (1) pumped by a seed pump (2), an amplifier (3) pumped by an amplifier pump (4), a controller (5), and a scanner (6), wherein the controller (5) controls the seed pump (2), the amplifier pump (4) and the scanner (6) in synchronism such that optical pulses (10) emitted by the seed laser (1) are propagated through the amplifier (3) and directed to the material (8) by the scanner (6), the apparatus being characterized in that controller (5) controls the amplifier pump (4) to cause the amplifier (3) to act as an optical attenuator when the optical radiation (7) is in a first power range, and as an optical amplifier when the output power is in a second power range.

摘要： The invention relates to an optical amplifier, in particular for optical fiber telecommunication lines (1), operating with a transmission signal in a predetermined wavelength range, which amplifier comprises a fluorescent active optical fiber (6) doped with erbium, having two cores (11 and 12, 101 and 102), one (11, 101) of which is connected to a fiber (4) in which a transmission signal to be amplified and a luminous pumping energy are multiplexed, and to an outgoing fiber adapted to transmit the amplified signal, whereas the second core (12, 102) is optically coupled to the first core and is capable of absorbing the spontaneous erbium emission which would constitute a noise source, allowing a signal to be amplified in a wavelength range substantially corresponding to the tolerance range of the commercially available signal laser emitters.
