Yeo, K. S. and Mahdi, Mohd Adzir and Mohamad, H. and Hitam, Salasiah and Mokhtar, Makhfudzah (2009) Widely tunable Raman ring laser using highly nonlinear fiber. Laser Physics, 19 (12). pp. 2200-2203. ISSN 1054-660X


An all-optical widely tunable Raman fiber laser has been realized by incorporating a highly nonlinear fiber in a ring cavity. By feedback a portion of Raman Stokes wave back into the highly nonlinear gain medium, a Raman fiber laser is generated. We found that the lasing wavelength of Raman fiber laser can be tuned from 1537 to 1568 nm with peak power fluctuation within 1 dB, giving a total wavelength tunability of 31 nm. The optical signal-to-noise ratio is found to be wavelength dependent, and the highest optical signal-to-noise ratio of about 59 dB is recorded. The lasing threshold of the Raman fiber laser with this configuration is found to be as low as 300 mW
