摘要：
A Bi2O3-based erbium-doped fiber (Bi-EDF) ring laser with a 70 nm tunable range is demonstrated with a 49 cm long Bi-EDF in which tuning range can be extended to larger than 100nm using an optical switch to alter the length of Bi-EDF in the laser cavity. With an extinction ratio of better than 60 dB throughout the entire tuning range, the measured FWHM of laser lines are measured to be 0.09 nm. In addition, the common amplification parameters are measured and studied in detail for various pumping configurations.
