1.1–1.6 μm Multi-Wavelength Random Raman Fiber Laser
Multi-wavelength fiber lasers have attracted great attention due to their application value in many fields. In this work, we demonstrated a seven-wavelength random Raman fiber laser in the range of 1.1–1.6 μm. A piece of 1-km-long high Raman gain optical fiber is utilized as the gain medium. The 1st...

description | Multi-wavelength fiber lasers have attracted great attention due to their application value in many fields. In this work, we demonstrated a seven-wavelength random Raman fiber laser in the range of 1.1–1.6 μm. A piece of 1-km-long high Raman gain optical fiber is utilized as the gain medium. The 1st-order to 7th-order Stokes waves are located, respectively, at 1133 nm, 1194 nm, 1260 nm, 1332 nm, 1414 nm, 1504 nm, and 1606 nm. In the 3-dB bandwidth of optical spectra of 1st-order and 2nd-order Stokes waves, four peaks with an average spacing of 1 nm and 20 peaks with an average spacing of 0.45 nm respectively, are recorded. Pumped by a 1080 nm/12.5 W/220 ns laser, the maximum output power can reach 4.16 W, corresponding to the optical-to-optical conversion efficiency of ~30.7%. |
