| 英文摘要 | An optical coupler for coupling a signal light beam from a signal port (100) and a pump light beam from a pump port (110) into a common port (120) for coupling the pump and signal beams into a double-clad (DC) optical fiber (122) comprising a core (123), an inner clad (124) and an outer clad (125). The DC optical fiber has a section of coreless fiber (128) joined to it to form an extension piece. A free-space optical arrangement (130) combines the pump and signal light beams onto the common port so that the signal light beam is focused onto the core aperture at the buried interface (121) between the DC optical fiber and the coreless extension piece. The high power density signal beam focus is thus moved away from a more sensitive air:glass interface into a buried interface which has a higher damage threshold. In this way, higher signal beam powers can be handled. The invention allows higher power DC pumped amplifiers and lasers to be fabricated. |
