Intensity profile in a distributed feedback fiber laser characterized by a green fluorescence scanning technique
We report on an experimental technique for investigating the intensity profile in distributed feedback fiber lasers. By scanning along the laser length and monitoring the side green fluorescence, the intensity distribution in the laser can be inferred. With this approach, we experimentally verify th...

| Zusammenfassung: | We report on an experimental technique for investigating the intensity profile in distributed feedback fiber lasers. By scanning along the laser length and monitoring the side green fluorescence, the intensity distribution in the laser can be inferred. With this approach, we experimentally verify the sharply peaked intensity distribution predicted for λ/4 phase-shifted distributed feedback lasers. |
