“…Sub-ten-nanosecond fibre lasers with 100-W-class average power and several mJ of pulse energy became possible. 18,19 Furthermore, these fibres are the basis of mJ-level femtosecond fibre amplifiers, which are routinely operated in state-of-the-art fibre chirped-pulse amplification systems. 20 The reproducible fabrication of this first VLMA-PCF design with its arrangement of tiny air holes (necessary for the effective single-mode operation of these few-mode fibres) is extremely challenging.…”

Rare earth-doped fibres are a diode-pumped, solid-state laser architecture that is highly scalable in average power. The performance of pulsed fibre laser systems is restricted due to nonlinear effects. Hence, fibre designs that allow for very large mode areas at high average powers with diffraction-limited beam quality are of enormous interest. Ytterbium-doped, rod-type, large-pitch fibres (LPF) enable extreme fibre dimensions, i.e., effective single-mode fibres with mode sizes exceeding 100 times the wavelength of the guided radiation, by exploiting the novel concept of delocalisation of higher-order transverse modes. The non-resonant nature of the operating principle makes LPF suitable for high power extraction. This design allows for an unparalleled level of performance in pulsed fibre lasers.

“…As a new type of photonic crystal fiber (PCF), all-solid microstructured fiber shows versatile transmission characteristics and physical phenomena owing to the solid materials periodically distributed in the cladding with different refractive indexes (RI), which is similar to the microstructured fiber with airholes [1][2][3][4][5][6][7]. It is easier to splice and couple with conventional single-mode fibers (SMFs) without airhole collapse.…”

An all-solid waveguide array fiber (WAF) is one kind of special microstructured optical fiber in which the higher-index rods are periodically distributed in a lowindex silica host to form the transverse two-dimensional photonic crystal. In this paper, one kind of multidimensional microstructured optical fiber photonic device is proposed by using electric arc discharge method to fabricate periodic tapers along the fiber axis. By tuning the applied magnetic field intensity, the propagation characteristics of the all-solid WAF integrated with magnetic fluid are periodically modulated in both radial and axial directions. Experimental results show that the wavelength changes little while the transmission loss increases for an applied magnetic field intensity range from 0 to 500 Oe. The magnetic field sensitivity is 0.055 dB/Oe within the linear range from 50 to 300 Oe. Meanwhile, the all-solid WAF has very similar thermal expansion coefficient for both high-and low-refractive index glasses, and thermal drifts have a little effect on the mode profile. The results show that the temperatureinduced transmission loss is < 0.3 dB from 26°C to 44°C. Further tuning coherent coupling of waveguides and controlling light propagation, the all-solid WAF would be found great potential applications to develop new micro-nano photonic devices for optical communications and optical sensing applications.

“…Conventional active step-index fibers with reduced numerical aperture, assisted by coiled or tapered sections to achieve singlemode operation, allow for core diameters of up to 40 µm. Rare-earth-doped photonic crystal fibers (PCFs) allow for significantly larger core sizes of up to 100 µm [8][9][10] due to the significantly better control of the index step between a nanostructured core and the holey photonic crystal cladding. Due to the PCF cladding's design freedom, an additional functionality, such as polarizing or polarization maintaining properties, can be added [11].…”

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
