From: Dissipative soliton generation and real-time dynamics in microresonator-filtered fiber lasers

a Schematic of experimental setup. ISO: isolator, WDM: wavelength division multiplexer, HWP: half-wave plate, PBS: polarizing beam splitter, L1 and L2: lens, BPF: band-pass filter. b Transmission and reflection of the FFP microresonator. c Spectrum of the single soliton. Inset: RF beat note of the soliton repetition rate. d SSB phase noise spectrum of the single soliton. e RIN of the single soliton and the EDFA pump. f SSB frequency noise spectra of a comb line and a conventional ECDL (Toptica, CTL1550)
