Figure 4From: Conception, modelling, and characterization of a fiber amplifier with a simple and easy-to-repair configuration intended for the use in harsh environmentsPump power characteristics of the developed YDFA. Curve represents the numerical simulation with the parameters \(L_{\mathrm{fiber}}=4.7~{\mathrm{m}}\), \((\varepsilon _{S},\varepsilon _{P},\varepsilon _{r})=(0.326,0.8,0.02)\), and \(P_{S} = 0.2~{\mathrm{W}}\). Horizontal axis is the optical power launched into the YDF, i.e. \(\varepsilon _{P}P_{P}\)Back to article page
