“…Using the Collins formula, [50,51] we simulated theoretically the light evolution over free-space propagation, unveiling the formation process of phase singularity in the centroid of the light beam. The simulated results of the optical-vortex beam with a topological charge of |l| = 1 are illustrated in Figure 2.…”

Femtosecond light pulses carrying optical angular momentums (OAMs), possessing intriguing properties of helical phase fronts and ultrafast temporal profiles, enable many applications in nonlinear optics, strong‐field physics, and laser micromachining. While generation of OAM‐carrying ultrafast pulses and their interactions with matters are intensively studied in experiments, 3D characterization of ultrafast OAM‐carrying light beams in spatiotemporal domain has, however, proved difficult to achieve. Conventional measurement schemes rely on the use of a reference pulsed light beam, which needs to be well characterized in its phase front and to have sufficient overlap and coherence with the beam under test, largely limiting practical applications of these schemes. Here a self‐referencing set‐up is demonstrated based on a tilted interferometer that can be used to measure complete spatiotemporal information of OAM‐carrying femtosecond pulses with different topological charges. Through scanning one interferometer arm, the spectral phase over the pulse spatial profile can be obtained using the tilted interference signal, and the temporal envelope of the light field at one particular position around its phase singularity can be retrieved simultaneously, enabling 3D beam reconstruction. This self‐referencing technique, capable of measuring spatiotemporal ultrafast optical‐vortex beams, may find many applications in fields of nonlinear optics and light–matter interactions.

“…Femtosecond optics is also actively developed last decades [15][16][17][18]. Ultrashort optical vortices [19,20] as well as ultrashort cylindrical vector beams (CVB) [21,22] are shown to have special properties at the focus: high intensity, low exposure duration and orbital angular momentum. These features open up new possibilities in different technical and scientific areas [23][24][25].…”

In this research, the process of focusing of femtosecond cylindrical vector beam with second order by binary zone plate is studied applying the frequency-dependent finite-difference time-domain method. We have demonstrated that the material of zone plates significantly influenced on the electromagnetic field formed at the focus. We also shown that, tight focusing of a second-order cylindrically polarized laser pulse produced an energy backflow in the focal plane of phase and aluminum binary zone plates. However, there is no reverse energy flux in the focus of binary zone plate made in thin gold film.

“…Therefore, some investigations have been reported [32]- [38], which uses the vortex pulsed beam to decrease pulse broadening caused by turbulence. In the focal plane, the spatial pulse shaping of Laguerre-Gaussian pulsed beams was analyzed by Martínez-Matos et al [33], which revealed the topological charge drastically jumping with evolving the pulse in time. In free space, Nie et al [32] studied the spatiotemporal coupling characteristics and the intensity distribution variations of ultrashort Gaussian vortex pulse, and found that the topological charge number of the beam will affect the intensity and the spatiotemporal coupling.…”

By developing the complex phase perturbation for vortex pulsed beams in asymmetric oceanic turbulence and the spatiotemporal orthogonal basis for Lommel-Gaussian pulsed beam, we establish the received probability model of orbital angular momentum (OAM) modes for vortex pulsed beams propagating through asymmetric oceanic turbulence. Using this new model, we investigate the received probability and the pulse broadening of OAM modes of Lommel-Gaussian pulsed beam in asymmetric oceanic turbulence. Numerical simulation results show that Lommel-Gaussian pulsed beam causes a smaller pulse broadening when it propagates through oceanic turbulence with higher asymmetric factor, lower temperature structure constant, smaller inner scale and outer scale. In addition, Lommel-Gaussian pulsed beam with lower carrier frequency propagates through the oceanic turbulence with higher asymmetric factor, larger inner scale, smaller outer scale and smaller temperature structure constant, which obtains a higher received probability of signal OAM modes. For Lommel-Gaussian pulsed beams, the change of OAM quantum number has a week effect on the pulse broadening and the received probability.
