“…That is to say, the TPF intensity appears with periodical modulation and the modulation depends on the LP component of the excited light. This experimental observation is in good agreement with previous studies on polarization control of supercontinuum generation [22,23]. No difference was found in the TPF intensity between right and left CP light for this complex solution.…”

Polarization-induced fluorescence modulation behavior of a self-assembled coordination cage-shaped complex was investigated using femtosecond laser pulses. The variations of the total two-photon-induced fluorescence (TPF) intensity were found to be strongly modulated by different polarized incident lights and tightly dependent on the linearly polarized component of the excited light. The polarization-induced modulation efficiency of the TPF underwent intensity-dependent decrease, which could be attributed to the two-photon-induced excited-state absorption. The nonlinear absorption behavior of the complex was also studied by performing both femtosecond open aperture Z-scan and nonlinear transmission measurements, which help to better understand the intrinsic optical properties of the molecule and portend its practical applications.

“…The first approach relies on tailoring and shaping the parameters of the input laser beam and pulse. To this end, a certain control of filamentation and SC generation processes was achieved by varying the polarization state (from linear to circular) of the incident radiation in isotropic media [255,256] and by choosing either ordinary or extraordinary input pulse polarizations in birefringent media with zero second-order susceptibility, e.g. α-BBO crystal [228].…”

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.

“…During the generation of SC in PCF, higher-order dispersion (HOD), self-steepening (SS), and stimulated Raman scattering (SRS) play important roles. Therefore, the Mechanism of supercontinuum generation in PCF is more complex than traditional fibers [9][10][11][12] . The earlier work considered the supercontinuum spectrum generation in a certain dispersion curve.…”

It has been investigated of nonlinear propagation of femosecond pulse and supercontinuum generation (SCG) in three photonic crystal fibers (PCFs) with different dispersion profile in the 1550nm window by numerical stimulation. The influence of higher-order effects on supercontinuum, including higher-order dispersion (HOD), self-steepening (SS), and stimulated Raman scattering (SRS), are discussed in detail as well. The results of numerical simulations show that group velocity dispersion and self-phase modulation take main effect in the initial stage. In the PCF with anomalous dispersion, SRS plays main role when the propagation distance increases, which induces a red-shift of the central wavelength, suggesting the appearance of soliton self-frequency shift. In the PCF with near-zero anomalous dispersion, HOD plays main role. This results in the fission of higher-order solitons and remarkable broadening of the pulse spectrum. In the PCF with normal dispersion, higher-order effects have almost no effect on the pulse. The Gaussian pulse wave broadens to rectangular symmetrically, and the pulse spectrum broadens symmetrically, too. However, the broadening is smaller than the former two cases.
