| 英文摘要 | The present invention discloses a method for eliminating, or at least minimizing, the locking range variability of laser modules which employ external grating, such as fiber bragg gratings. It has been observed that the coupling efficiency between the laser and its output fiber is a highly variable property of the laser module, causing variations in the laser module's locking range. The laser module's locking range, however, can be readily reset to or near its nominal value by measuring the laser module's coupling efficiency, and then judiciously choosing a grating having a peak reflectivity which compensates for variations in the coupling efficiency by maintaining constant the effective reflectivity Reff of the fiber/grating combination. |
