READ ME File For 'Dataset for Multimode Raman Pumping for Power Scaling of Large Area Higher Order Modes in Fiber Amplifiers' Dataset DOI: 10.5258/SOTON/D0251 ReadMe Author: Sheng Zhu, University of Southampton This dataset supports the publication: Multimode Raman Pumping for Power Scaling of Large Area Higher Order Modes in Fiber Amplifiers Contents +++++++++ This dataset contains which are used for generating Fig.1, Fig.3(a)(b)(c) and Fig.4(a)(b). These figures are plotted using Origin 2017. The figures are as follows: Fig. 1 BPM simulations of evolution of gain (dotted curve) and normalized power of pump (dashed) and signal (solid) in FRA (red) & YDFA (black). Fig. 3(a) Measured average-power fiber gain (disregarding coupling losses) against launched peak pump power. Fig. 3(b) Spectra of amplified signal with 0.5 nm resolution; Fig. 3(c) Pump pulses before (black curve) and after (red curve) Raman amplification at 18 dB signal gain; Input signal (fuchsia curve); Output signal (blue curve) at 16 dB gain. Fig. 4 Signal-beam line profiles at output of Raman amplifier fiber (a) without pump and (b) with 18 dB gain.
