Optical spectra of input and output light of the fibre resonator.
(a) Spectrum of the input light consisting of a single pump frequency (P). The inset shows the temporal measurement of a 500 ns input pulse. (b) Averaged output spectrum of the fibre resonator for about 0.7 W input peak power. Besides the pump (P), Stokes waves (1S–3S) at longer wavelength as well as anti-Stokes waves (1AS, 2AS) at shorter wavelengths are visible.
