“…This can be achieved only by having a much higher repetition rate (100 Hz-1 kHz) and a high power laser system. Looking at current developments in laser technology [42][43][44], it appears quite feasible in the near future. Next, the production of 11 C isotope by low energy deuteron beam can be increased substantially, firstly by using enriched 10 B, which is available commercially in place of natural boron and secondly by removing the hydrogen contamination from the CD 2 foil which supresses the deuterium flux.…”

We report an experimental investigation on nuclear reactions using an intense, ultra-short laseraccelerated proton and deuteron beam generated by the interaction of 25 fs, 150 TW Ti: sapphire laser pulse with normal thin foils and foils containing deuterium atoms. The production of a positron-emitting short-lived 11 C radio-isotope from the interaction of protons and deuterium ions with a solid boron palette by means of 11 B (p, n) 11 C and 10 B (d, n) 11 C nuclear reactions was studied. The maximum radioactivity in the optimized laser irradiation condition was found to be 5.2 kBq per laser shot, which corresponds to ∼9×10 6 atoms of 11 C isotopes using the 11 B (p, n) 11 C reaction. The relative efficiency of 11 C production using a proton and deuteron beam was also explored experimentally. About 30 % enhancement in 11 C activity was observed with CD 2 coated targets. It was also found that because of the relatively low deuteron energy threshold of the reaction 10 B (d, n) 11 C, even the low energy part of the accelerated deuterons in the spectrum can be used for efficient 11 C production. In the same setup, the proton-induced fusion reaction in the boron target (p+ 5 B 11 ⇒3α+8.7 MeV) was also studied. The resultant fusion yield and alpha particle energy spectrum was measured.

“…Currently, laser systems delivering peak power of Terrawatts-level can operate in the laboratory environment only due to their size, weight, and frequent need for maintenance [14][15][16][17]. However, high peak power laser systems would be interested in a number of applications outside laboratory environments such as manufacturing and defense [11,16,[18][19][20].…”

A novel design of a grating-based optical pulse compressor is proposed. The proposed compressor provides a large group delay dispersion while keeping the compressor linear size small. The design of the proposed compressor is based on a traditional Treacy compressor with a straightforward modification of inserting two lenses between the compressor’s gratings. This simple alternation aims to substantially increase group delay dispersion of the compressor or alternatively to decrease the compressor size while maintaining its group delay dispersion. A theoretical description of the enhanced compressor has been developed in the paraxial approximation. A detailed numerical model has been built to calculate the compressor parameters more accurately. These theoretical studies have revealed that the enhanced optical compressor provides a significant increase in the group delay dispersion compared to a standard Treacy compressor.

“…However, OA-LDC and HP-MB-LDC methods typically require large facilities with multiple laser sources, e.g., the National Ignition Facility (NIF) or OMEGA Laser Facility [30], which have traditionally been outside the scope of many researchers. That said, the availability of high-peak-power lasers is growing rapidly, with new capabilities in short-laser pulse lasers becoming widely accessible at a reasonable cost [41][42][43][44].…”

The field of high-pressure materials research has grown steadily over the last seven decades, with many remarkable discoveries having been made. This work is part II of a three-part series summarising recent progress in laser material processing within diamond anvil cells (L-DACs); this article focuses on the practice of laser-driven dynamic compression within diamond anvil cells (i.e., LDC–DAC experimentation). In this case, materials are initially pre-compressed within diamond anvil cells, then further dynamically compressed through the use of a high-power pulsed laser, often with the intent to isentropically compress, rather than to heat samples. The LDC–DAC approach provides a novel route to much higher dynamic pressures (approaching 1 TPa), as compared to conventional static compression within a single-stage DAC (<300 GPa) and provides a route to mapping Hugoniot curves. Recent proliferation of low-cost, high-power laser sources has led to increased research activity in LDC–DAC materials processing over the last two decades. Through LDC–DAC experiments, a greater understanding of the properties/structure of cold- and warm-dense matter has been obtained, and novel material phases have been realised. In this article, LDC–DAC experimental methods are reviewed, together with the underlying physics of laser dynamic compression in confined spaces. In addition, a chronology of important events in the development of LDC–DAC processing is provided, and emerging trends, gaps in knowledge, and suggestions for further work are considered.
