An environmentally stable,repetition rate tunable,all-polarization-maintaining,Er-doped pulse fiber laser with a single-wall carbon nanotubes saturated absorber is demonstrated.The ring laser cavity includes a delay line enabling a tunable repetition rate to vary from 35.52 MHz to 35.64 MHz with continuous mode-locked operation.The laser output parameters confirm that the tunable mode-locked operations are stable.High environmental stability is also confirmed by the-130 dBc/Hz low phase noise,a 70-dB signal-to-noise ratio of radio frequency signals,a low amplitude fluctuation of5.76 × 10-4,and a low fluctuation of repetition rate of 12 Hz.The laser shows a high degree of polarization of 93%.
An environmentally stable, repetition rate tunable, all-polarization-maintaining, Er-doped pulse fiber laser with a single-wall carbon nanotubes saturated absorber is demonstrated. The ring laser cavity includes a delay line enabling a tunable repetition rate to vary from 35.52 MHz to 35.64 MHz with continuous mode-locked operation. The laser output parameters confirm that the tunable mode-locked operations are stable. High environmental stability is also confirmed by-130 dBc / Hz low phase noise, a 70-dB signal-to- noise ratio of radio frequency signals, a low amplitude fluctuation of 5.76 × 10-4, and a low fluctuation of repetition rate of 12 Hz.
