“…However, due to low efficiency, complexity and the heavy gauge, dye lasers could not be applied out of laboratory conditions. On the contrary, fibre lasers [21], which emerged in 1961, benefit from the maintenance-free operation, compactness and cost-effective design.…”

Carbon nanotubes (CNTs) possess both remarkable optical properties and high potential for integration in various photonic devices. We overview, here, recent progress in CNT applications in fibre optics putting particular emphasis on fibre lasers. We discuss fabrication and characterisation of different CNTs, development of CNTbased saturable absorbers (CNT-SA), their integration and operation in fibre laser cavities putting emphasis on stateof-the-art fibre lasers, mode locked using CNT-SA. We discuss new design concepts of high-performance ultrafast operation fibre lasers covering ytterbium (Yb), bismuth (Bi), erbium (Er), thulium (Tm) and holmium (Ho)-doped fibre lasers.

Abstract. This paper reviews recent progress on ultrashort pulse generation with erbium-doped fiber ring lasers. The passive mode-locking technique of polarization additive pulse mode-locking (P-APM) is used to generate stable, selfstarting, sub-500 fs pulses at the fundamental repetition rate from a unidirectional fiber ring laser operating in the soliton regime. Saturation of the APM, spectral sideband generation, and intracavity filtering are discussed. Harmonic modelocking of fiber ring lasers with soliton pulse compression is addressed, and stability regions for the solitons are mapped and compared with theoretical predictions. The stretchedpulse laser, which incorporates segments of positive-and negative-dispersion fiber into the P-APM fiber ring, generates shorter (sub-100 fs) pulses with broader bandwidths (> 65 nm) and higher pulse energies (up to 2.7 nJ). We discuss optimization of the net dispersion of the stretched-pulse laser, use of the APM rejection port as the laser output port, and frequency doubling for amplifier seed applications. We also review the analytical theory of the stretched-pulse laser as well as discuss the excellent noise characteristics of both the soliton and stretched-pulse lasers. 42.60F; 42.65; 42.80 Fiber lasers were made possible in the 1960s by the incorporation of trivalent rare-earth ions such as neodymium, erbium, and thulium into glass hosts [1]. Soon thereafter neodymium was incorporated into the cores of fiber waveguides [2,3]. Due to the high efficiency of the Nd +3 ion as a laser, early work focused on Nd +3 -doped silica fiber lasers operating at 1.06 µm [4]. Doping of silica fibers with Er +3 ions was not achieved until the 1980s [5,6]. Since that time Er +3 -doped fiber lasers have received much attention, because the lasing wavelength at 1.55 µm falls within the low-loss window of optical fibers and thus is suitable for optical fiber communications. Rare-earth ions such as Ho +3 [7,8], Tm +3 [9-11], and * Current address: Lucent Technologies/Bell Labs, 791 Holmdel-Keyport Road, Holmdel, NJ, USA * * Current address: NTT Access Network Systems Laboratory, Tokai-mura, Naka-gun, Ibaraki-ken 319-11, Japan Yb +3 [12,13] have also been used as dopants or co-dopants in silica or fluoride fibers, allowing new lasing or pumping wavelengths, and Pr +3 has been incorporated into fluoride fiber, providing emission at 1.3 µm [14,15]. PACS:Among the numerous advantages of fiber lasers are simple doping procedures, low loss, and the possibility of pumping with compact, efficient diodes. The fiber itself provides the waveguide, and the availability of various fiber components minimizes the need for bulk optics and mechanical alignment. Many different cavity configurations can be easily built with fibers and fused-fiber couplers, including linear FabryPerot, ring, and combinations of the two. Enhancement of the fiber nonlinearity due to large signal intensities and long interaction lengths is an additional advantage of fiber lasers that is particularly important for mode-locki...

“…In 1961, Elias Snitzer proposed and subsequently demonstrated that an optical fiber can be much more than a mere "light pipe": A fiber terminated with partially reflecting ends would be the analog of the Fabry-Perot interferometer resonant cavity discussed by Shawlow and Townes [1,2]. Since then, laser and fiber technology development have thrived closely connected: Today, world-spanning optical fiber networks rely on low-loss fibers [3] and on amplification in erbium-doped active fibers.…”

The use of ultrashort laser pulses for fiber grating inscription has many advantages in comparison to continuous wave and long pulse lasers. The most important one is that it allows inscription in nonphotosensitive fiber materials. In this paper the principal inscription techniques and the physical properties of femtosecond (fs) pulse written in-fiber gratings are reviewed. The role of focusing and order walk-off on the inscribed structures is emphasized. A fs pulse written fiber Bragg grating (FBG) also has a unique coupling behavior, due to a refractive index change that is independent from the fiber geometry. Selected applications of such gratings for sensing and fiber lasers are discussed.
