摘要/描述

A simple technique for achieving wavelength tunable andamplitude-equilibrium dual-wavelength fiber laser source based on adual-pass Raman/Brillouin amplification configuration is proposed andexperimentally investigated. A stable room-temperature dual-wavelengthlasing oscillations with average channel power of more than 1 mW andsignal-to-noise ratio of more than 30 dB were obtained with only 250 mWRaman pump power. The dual-wavelength lasing oscillations withwavelength spacing of 0.076nm were so stable that the maximum powerfluctuations and wavelength shifts over more than 10 minutes of observationwere less than 0.5 dB and 0.002nm, respectively. The dual-wavelengthlasing output can also be tuned in a range of -35nm from 1545.090nm to 1580.078nm with an amplitude-equilibrium of less than a peak powerdifference of 0.25 dB at the two wavelengths.
