“…3 A laser based on double-clad Yb fiber produced 11.8 nJ chirped pulses (110 mW average power), which were dechirped to 200 fs outside the laser. 4 This laser contained two pairs of diffraction gratings in the cavity along with an acousto-optic modulator to initiate mode locking. Much of the laser cavity is actually not fiber; the unguided propagation and low efficiency of this laser naturally counter some of the main benefits of fiber sources.…”

A series of experiments aimed at determining the maximum pulse energy that can be produced by a femtosecond fiber laser is reported. Exploiting modes of pulse propagation that avoid wave breaking in a Yb fiber laser allows pulse energies up to 14 nJ to be achieved. The pulses can be dechirped to sub-100-fs duration to produce peak powers that reach 100 kW. The limitations to the maximum pulse energy are discussed.

“…In particular, with small net positive cavity dispersion, the pulse energy is larger than that produced in the soliton regime. Stretched pulse lasers with output energies from tens of picojoules to some nanojoules have been reported [18][19][20][21][22] before nonlinearity provokes instabilities. However, under certain circumstances nonlinearity can be advantageous.…”

This chapter reviews the fundamentals and achievements of ultrashort pulse generation and amplification in ytterbium-doped fibers. Compact and ultrastable passively mode-locked fiber oscillators represent an ideal seed source for high performance femtosecond fiber amplification systems, which have been scaled towards kW-level average power and pulse energies well above the mJ-level. These laser systems will have significant impact in numerous scientific and industrial applications. Introduction and MotivationA number of important practical as well as fundamental research applications of ultrafast lasers appeared over the last decades, a trend initiated by the step from old dye-laser technology towards solid-state lasers. These high-power ultrafast solidstate lasers use small rods as the amplifier media, for instance, Titanium-doped sapphire as the most widespread one and have the potential to generate significantly higher pulse energies, higher powers and shorter pulse durations in combination

“…The pulse width experiences large variations per cavity round trip, with a change in the chirp sign. Stretched-pulse lasers with output energies from tens of picojoules to some nanojoules have been reported [12][13][14]. The most fundamental limitation to pulse energy in a fiber oscillator arises from wave-breaking phenomena because of large nonlinearities.…”

Passive mode-locking in fiber lasers is investigated by numerical and experimental means. A nondistributed scalar model solving the nonlinear Schrödinger equation is implemented to study the starting behavior and intra-cavity dynamics numerically. Several operation regimes at positive net-cavity dispersion are experimentally accessed and studied in different environmentally stable, linear laser configurations. In particular, pulse formation and evolution in the chirped-pulse regime at highly positive cavity dispersion is discussed. Based on the experimental results a route to highly energetic pulse solutions is shown in numerical simulations.
