Figure 1

(a) The ring laser setup including a 976 nm pump diode, a power signal combiner (PSC), 9 m Yb-doped fiber, a cladding power stripper (CPS), a filter section made of a series of WDMs, 1.3 km passive fiber, and two output couplers (OC1 and OC2) for characterization. Two ends of the filter section are labeled (1 and 2) for later reference in Sect. “Seeding Raman”. (b) Transmission of the filter section in two different configurations in linear scale (top) and logarithmic scale (bottom). Note the additional loss around 1163 nm for the configuration with WDMs 1 to 4 compared to the one with WDMs 1 to 3 for additional suppression of SRS.
