“…SESAM technology based on quantum well structures involves also complicated molecular beam epitaxy (MBE). These weaknesses cause that the new class of materials like carbon nanotubes [5][6][7][8][9][10], graphene [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] and topological insulators [31][32][33] have been recently considered as broadband and cost effective SAs. First, single-walled carbon nanotubes (SWCNT) have been used as an effective SA [5].…”

“…Its extremely broad, flat and wavelength independent absorption characteristic [11,12] cause that graphene seems to be an universal SA for lasers operating in the near infrared. Since the first demonstrations of graphene mode-locked laser [10,13] a lot of works on graphene based lasers have been presented [10,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. The Q-switched operation of graphene-based lasers has been also presented [29,30].…”

In this paper we present a dual-wavelength fiber mode-locked laser based on CVD-graphene saturable absorber (SA). The laser setup is based on two ring cavities connected by a common branch with a graphene SA. As a gain media erbium (Er) and thulium (Tm) doped active fiber were used. The laser generate optical pulses centered at 1558.5 nm and 1937 nm. The repetition rates and pulse durations were of 23.2 MHz, 16.42 MHz and 0.95 ps, 1.03 ps for the solitons generated in Er-and Tm-doped cavities, respectively.

“…Since then various setups have been presented, utilizing erbium [33,34], and ytterbium [35]. There are several methods of preparing graphene suitable for mode-locking: 1) epitaxial growth by chemical vapor deposition (CVD) on various substrates (mostly Cu and Ni) [36], 2) direct exfoliation of natural graphite by ultrasonification it in various organic solvents e.g. dimethyloformamide (DMF) [37], 3) mechanical exfoliation of graphene from bulk graphite [38][39][40][41].…”

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.

“…Hereafter, pulses of 570 fs [28] in short-length cavities as well as 415 fs [29] in longlength cavities were demonstrated with multilayer CVD graphene samples. Pulse duration as short as 315 fs was obtained in EDFL using a CVD bilayer graphene samples [30].…”

We present a study on the characterization and quality evaluation of all-fiber chemical vapor deposition (CVD) graphene saturable absorber samples for Erbium-doped fiber laser (EDFL) mode-locking. Optical fiber end faces covered by CVD graphene were analyzed by Raman spectroscopy, and classification criteria related to graphene Raman bands properties were adopted in order to evaluate samples quality. The analysis revealed that for all samples the fiber core was 100% covered by graphene, with 88% average monolayer graphene coverage and 82% low defect graphene coverage. Graphene samples were used as saturable absorbers in Erbium-doped fiber laser, and solitonlike pulses as short as 599 fs were generated, with average pulse duration of 620 ± 10 fs among all samples.
