| 英文摘要 | A bidirectionally pumped optical amplifier comprises an active fibre having two ends, a first WDM coupler and a second WDM coupler coupled to said ends, a first pump branch coupled to said first WDM coupler comprising a first laser and a grating, for introducing pump radiation in said active fibre in a first direction, and a second pump branch coupled to said second WDM coupler comprising a second laser, for introducing pump radiation in said active fibre in a second direction, opposite to said first direction. A portion of unabsorbed pump residual propagating in the first direction is coupled in one of the two pump branches towards the pump laser included in the pump branch, and locks the emission wavelength of the pump laser. The other pump branch preferably comprises an optical isolator for the pump radiation. Preferably, the pump lasers emit in the 980 nm window. |
