READ ME File For 'Data for 'Dataset for Off-peak dual-wavelength multimode diode-laser-pumped fiber Raman laser' Dataset DOI: 10.5258/SOTON/D0549 ReadMe Author: Soonki Hong, University of Southampton This dataset supports the publication: Hong, S., Feng, Y., & Nilsson, J. (2018). Off-peak dual-wavelength multimode diode-laser-pumped fiber Raman laser. IEEE Photonics Technology Letters, 1-4. DOI: 10.1109/LPT.2018.2863559 This dataset contains: Fig. 1. Experimental setup. Inset graphs depict the reflectivity of DM1 and DM2 as well as the refractive index and GeO2 concentration profile of GRIN fiber. Fig. 2. FRL output power vs. launched total pump power. The labels on the curves indicate results for when (i) the 976-nm pump varies while the 950-nm pump is switched off, (ii) the 976-nm pump varies while the 950-nm pump is at maximum power (41 W), and (iii) the 950-nm pump varies while the 976-nm pump is at maximum power (49 W). Specifically, (ii)-(1) indicates the power of the primary signal at 1020 nm whereas (ii)-(2) indicates the power at 1000 nm (1st Stokes of the 950-nm pump), which is affected by a low reflectivity in DM2. The inset shows a 2D power distribution of maximum output power as created from orthogonal line scans. Fig. 3. Output spectra when (a) the 950-nm pump is switched off, (b) the 950-nm pump is at maximum power (41 W), (c) the 976-nm pump is at maximum power (49 W). In (b), (ii)-(1) indicates the primary signal (1020 nm) whereas (ii)-(2) (at 1000 nm) indicates 1st Stokes of the 950-nm pump. Fig. 4. Simulations, together with experimental data. High-power single wavelength 976-nm pumping (grey line) is also shown. Labeling as in Fig. 2.
