| 英文摘要 | An active device comprising a length of doped fibre (1) and an end-coupled pump source (11). The fibre (1) is of single-mode geometry and incorporates rare-earth or transition metal dopant ions. These latter are incorporated at a low-level uniform concentration (< 900 ppm). The fibre host (1) selected exhibits an inherently ultra low attentuation loss (<40 dB/km) at the emission wavelength. The fibres (1) are generally of long length (e.g. 5 m to 300 m) and may be coiled for compact packaging. The fibre (1) may be formed as part of a Fabry-Perot cavity (1, 7, 9); or, as a ring cavity (fig. 8) using a doped fibre coupler (29) spliced to form a ring (27). Q-switch and mode-locking devices (19) and gratings (25) may be included as part of the Fabry-Perot cavity to allow pulse-mode operation and/or wavelength tuning, respectively. The fibre (1) may be utilised as an amplifier and a coupler arrangement (fig. 10) is described. Examples are given for devices using Neodymium, Erbium or Praseodymium doped-fibre. |
