We put forward a co-axial pump(optical)-probe(X-rays) experimental concept and show performance of the optical component. A Bessel beam generator with a central 100 micrometers-diameter hole (on the optical axis) was fabricated using femtosecond (fs) laser structuring inside a silica plate. This flat-axicon optical element produces a needle-like axial intensity distribution which can be used for the optical pump pulse. The fs-X-ray free electron laser (X-FEL) beam of sub-1 micrometer diameter can be introduced through the central hole along the optical axis onto a target as a probe. Different realisations of optical pump are discussed. Such optical elements facilitate alignment of ultra-short fs-pulses in space and time and can be used in light-matter interaction experiments at extreme energy densities on the surface and in the volume of targets. Full advantage of ultra-short 10 fs X-FEL probe pulses with fs-pump(optical) opens an unexplored temporal dimension of phase transitions and the fastest laser-induced rates of material heating and quenching. A wider field of applications of fs-laser-enabled structuring of materials and design of specific optical elements for astrophotonics is presented.

“…[81][82][83] The choice of the carrier waves decides how the spiral beams are delivered in 3-D space. This same principle has been used to generate a variety of exotic complex light with OAM, such as Mathieu beams, 84 achromatic vortices, 85 modulated optical vortices, 86 optical-vortex filaments, 63 spiraling higher-order Bessel beams, 87 beams with fractional topological charges, 88,89 and perfect vortex beam. 90,91 The disadvantages of employing an HOE for the generation of special beams carrying OAM, such as lower efficiency, are discussed in Ref.…”

Orbital angular momentum (OAM), one of the most recently discovered degrees of freedom of light beam field has fundamentally revolutionized optical physics and its technological capabilities. Optical beams with OAM have enabled a large variety of applications, including super-resolution imaging, optical trapping, classical and quantum optical communication, and quantum computing, to mention a few. To enable these and several other emerging applications, optical beams with OAM have been generated using a variety of methods and technologies, such as a simple astigmatic lens pair, one-/two-dimensional holographic optical elements, threedimensional spiral phase plates, optical fibers, and recent entrants such as metasurfaces. All these techniques achieve spatial light modulation and can be implemented with either passive elements or active devices, such as liquid crystal on silicon and digital micromirror devices. Many of these devices and technologies are not only used for the generation of amplitude phase-polarization structured light beams but are also capable of analyzing them. We have attempted to encompass a wide variety of such technologies as well as a few emerging methodologies, broadly categorized into generation and detection protocols. We address the needs of scientists and engineers who desire to generate/detect OAM modes and are looking for the technique (active or passive) best suited for their application. © The Authors.

The optical pupil filter is regarded as one of the most important devices in the manipulation of intensity distribution in the focal volume. The effect of different incident light distributions on the superresolution performance and the depth of focus (DOF) of superresolsing pupil filters are studied based on the scalar diffraction theory of light. The results indicate that there is little change of superresolution performance and DOF extension when the light with Gauss function distribution incidents compared with uniform light incidence with equal total incident light energy; little change of spot compression ratio is shown, the Strehl ratio is lower and the DOF is extended when the incident light with Gauss function distribution incidents; while for the incident light with the first order Bessel function, the spot compression ratio and the DOF decrease, the Strehl ratio gets large increase. In general, superresolution can be more easily realized with more light intensity distributed along the verge of the pupil, and the increase of either Strehl ratio or DOF is based on sacrifice of the other one.
