| 英文摘要 | A laser system has an input waveguide 4 which receives an optical input signal from an optical amplifier 3. Partial reflecting means 5 for example, a Bragg grating, receives an optical input signal from the input waveguide and reflects a portion of the optical input signal back along the input waveguide. The reflecting means 5 and the optical amplifier 3 define a resonant cavity. A reflection photodetector means 30 detects light reflected back by the partial reflecting means 5 and supplies an electrical output signal indicative of the reflected light. Phase modulation means modulates the phase of the optical input signal. Control means controls the phase modulation means in dependence on the electrical output signal from the reflection photodetector means in order to provide a stabilised optical output signal. Preferably, a transmission photodetector 6 detetcts the optical output signal and supplies an electrical output signal indicative of the output signal. |
