“…In prac− tice, the number of wave plates depends on multiple factors and can vary. In some examples two full polarization con− trollers are used (one before and one after polarization beam splitter) [18], in some setups proper position of the fibre guarantees that mode−locking will be obtained with only one PC (placed before PBS) [19]. Other examples include two [20], three [21] or four [22] wave plates.…”

In this paper we present a novel configuration of an NPR mode-locked Er-doped laser. This new optical setup uses voltage controlled LC cells to replace standard retarders (quarter-and half-waveplates) inside the laser cavity. Using this novel, mechanical-adjustment-free setup a mode-locking was obtained with sub-500 fs pulse duration and an average power exceeding 40 mW. Presented results show that using simple LC cells, an optical layout of an NPR mode-locked laser can be greatly simplified.

“…2. The mode−locked fibre laser generating 200−fs pulses at 1560 nm with 169−MHz repetition frequency was used as a pump source [32]. The signal was directed to the SA through a variable optical attenuator (VOA) and a fibre coupler.…”

Erbium-doped fibre laser mode-locked by a graphene saturable absorber is presented. Pulses with 630-fs duration and 41.9-MHz repetition frequency were achieved at the centre wavelength of 1562 nm and 9-nm FWHM bandwidth. Multilayer graphene was obtained by mechanical exfoliation from a pure graphite block by using the scotch-tape method and deposited on a fibre ferrule to form a saturable absorber. The laser operated in a mode-locked regime with 37-mW pumping and 4-mW output power.

“…Up till now, the highest repetition rates from all-fiber NPR lasers in ring resonators were achieved in our group. In 2010, Nikodem et al demonstrated a fundamentally mode-locked Er-fiber laser with 169 MHz mode spacing and 111 fs pulse duration [17]. One year later Sobon et al presented a setup based on Er/Yb double-clad fiber capable of generating 10 GHz pulse trains in harmonic mode-locking regime [18].…”

Abstract. For the last decade a very attractive field of laser physics, namely the optical frequency comb technique, has been intensively developed. Fiber lasers play particular role in that area. The motivation of their development is obtaining broadband comb systems with well-defined and stable mods (comb teeth). This paper presents a basic overview devoted to the fiber-based optical frequency combs.
