“…Notably, other technologies are fortunately entering the field, in particular binary lithographic gratings that provide a valuable contribution especially for high dispersion DEs. Such gratings can be produced by using lithographic [10][11][12] or holographic 13,14 approach and they show an apparent versatility and large gratings can be produced. Notwithstanding these possibilities, they cannot be considered the final solution.…”

Volume Phase Holographic Gratings (VPHGs) are optical dispersing element widely used in astronomical spectrographs. In the last years, the availability of high performance photopolymers allowed for the development of innovative approaches to produce these dispersing elements. The key activities that have been carried out are: i) a production process based on photopolymeric holographic materials (in particular Bayfol ® HX by COVESTRO AG) was defined; ii) high quality VPHGs > 170 mm in diameter were manufactured; iii) innovative configurations to increase the dispersion/spectral range were implemented. The effectiveness of these activities is confirmed by the fact that more than 10 devices are mounted on observing facilities and several more are in development or planned. In this paper, we present the VPH technology based on photopolymers.

“…The highest laser intensity available at the moment is delivered by high-power petawatt (PW) lasers [7] and can realize intensities up to ∼10 23 W cm −2 after being focused [8]. With the increasing peak intensity of lasers, manipulation of such high-power lasers has become increasingly challenging because the size of the traditional solid-state optical components must be enlarged to avoid laserinduced thermal damage [9], which can be extremely costly and technically challenging for large-scale PW laser systems [10]. As a result, plasma-based optical components composed of free electrons and ions, which are not limited by * Authors to whom any correspondence should be addressed.…”

Plasma-based optics has emerged as an attractive alternative to traditional solid-state optics for high-power laser manipulation due to its higher damage threshold. In this work, we propose a plasma zone plate (PZP) driven by the pondermotive force of a Laguerre-Gaussian beam when it irradiates an underdense plasma slice. We formulate the theory of the PZP and demonstrate its formation and functioning using particle-in-cell simulations. The proposed scheme may offer a new plasma-based method to manipulate high-power lasers.

As a result, plasmabased optical components composed of free electrons and ions, which are not limited by optical damage as the traditional solid-state optical components, have become potential alternatives for high-power laser manipulation and have been extensively studied in recent years [11][12][13][14][15][16][17][18][19][20][21][22][23].…”
