“…A typical SC spectrum produced in fused silica extends from 390 to 1000 nm, as reported under various experimental conditions [131,132,[146][147][148][149]. Although similar, but somewhat narrower SC spectra were generated in BK7 [146,150,151] and ZK7 [152] glasses, which possess smaller bandgaps.…”

“…These practical issues are universal and hold for any nonlinear medium and at any input wavelength in the optical range. First of all, the optical damage of the medium is the major limiting factor in SC generation, therefore the external focusing condition (the numerical aperture, NA) should be carefully chosen [131,132]. Figure 7 shows the experimentally measured threshold energies for SC generation and optical damage in fused silica as functions of the numerical aperture [132].…”

Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media leads to a specific propagation regime, termed femtosecond filamentation, which in turn produces dramatic spectral broadening, or superbroadening, termed supercontinuum generation. Femtosecond supercontinuum generation in transparent solids represents a compact, efficient and alignment-insensitive technique for generation of coherent broadband radiation at various parts of the optical spectrum, which finds numerous applications in diverse fields of modern ultrafast science. During recent years, this research field has reached a high level of maturity, both in understanding of the underlying physics and in achievement of exciting practical results. In this paper we overview the state-of-the-art femtosecond supercontinuum generation in various transparent solid-state media, ranging from wide-bandgap dielectrics to semiconductor materials and in various parts of the optical spectrum, from the ultraviolet to the mid-infrared spectral range. A particular emphasis is given to the most recent experimental developments: multioctave supercontinuum generation with pumping in the mid-infrared spectral range, spectral control, power and energy scaling of broadband radiation and the development of simple, flexible and robust pulse compression techniques, which deliver few optical cycle pulses and which could be readily implemented in a variety of modern ultrafast laser systems.

“…However, for self-trapping of the laser beam over a length of several millimetres, the incident peak power needs to be significantly larger than the threshold for critical self-focusing. The length and threshold for a filament depends on the focusing conditions [106]. Loose focusing shows larger thresholds but results in longer filaments [107].…”

Ultrafast-laser-inscribed 3D integrated photonics: challenges and emerging applications

Since the discovery that tightly focused femtosecond laser pulses can induce a highly localised and permanent refractive index modification in a large number of transparent dielectrics, the technique of ultrafast laser inscription has received great attention from a wide range of applications. In particular, the capability to create three-dimensional optical waveguide circuits has opened up new opportunities for integrated photonics that would not have been possible with traditional planar fabrication techniques because it enables full access to the many degrees of freedom in a photon. This paper reviews the basic techniques and technological challenges of 3D integrated photonics fabricated using ultrafast laser inscription as well as reviews the most recent progress in the fields of astrophotonics, optical communication, quantum photonics, emulation of quantum systems, optofluidics and sensing.

“…Exceeding the critical power results in self-focusing and laser-pulse filamentation. 3 Recently, femtosecond laser pulses have been used to write three-dimensional waveguide structures in a variety of bulk glass samples. 4,5 Furthermore, long period gratings 6 as well as fiber Bragg gratings 7 have been realized by modification of the core index in germanosilicate fibers.…”
