“…Then the single pulse per cavity round-trip will break up into multiple, uncontrolled (untimed) pulses. Such pulse energy quantization has been observed and reported in figure-8 lasers [71,72] and in a long ring laser [28]. The all-fiber soliton laser of [29], however, could operate with a stable, single pulse per round-trip.…”

“…Rare-earth-doped fiber lasers are also susceptible to Q-switching due to their long upper-state lifetimes. Passive mode-locking of fiber lasers to generate subpicosecond pulses has been achieved using three main methods: nonlinear amplifying loop mirror [24][25][26], nonlinear polarization rotation (also called polarization additive pulse mode-locking or Kerr mode-locking) [27][28][29], and semiconductor saturable absorbers [30][31][32].…”

“…Simulations of a soliton fiber ring laser showed that a saturable absorber (nonlinear polarization rotation) and frequency limiter were required for the ring laser to self-start [38]. A self-starting ring cavity with low-birefringence fiber was then demonstrated at 1.55 µm, although the 1.2-ps soliton pulses were randomly spaced in bunches at the round-trip frequency [28]. Stable, self-starting, sub-500 fs soliton pulses at the fundamental repetition rate were first demonstrated in a short unidirectional ring [29].…”

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...

We consider an Yb-doped double-clad fiber laser in a unidirectional ring cavity containing a polarizer placed between two half-wave plates. Depending on the orientation of the phase plates, the laser operates in continuous, Qswitch, mode-lock or unstable self-pulsing regime. An experimental study of the stability of the mode locking regime is realized versus the orientation of the half-wave plates. A model for the stability of self-mode-locking and cw operation is developed starting from two coupled nonlinear Schrödinger equations in a gain medium. The model is reduced to a master equation in which the coefficients are explicitly dependent on the orientation angles of the phase plates. Analytical solutions are given together with their stability versus the angles.

This technique has been successfully used to obtain short pulse generation in different rare-earth doped fiber lasers [3]- [5], [12]- [15] and is self-starting.

We investigate theoretically a fiber laser passively mode-locked with nonlinear polarization rotation. A unidirectional ring cavity is considered with a polarizer placed between two sets of a halfwave plate and a quarterwave plate. A master equation is derived and the stability of the continuous and mode-locked solutions is studied. In particular, the effect of the orientation of the four phase plates and of the polarizer on the mode-locking regime is investigated.
