“…When researching and finalizing various weapons and equipment, in addition to the killing energy of the arms and the destroying effect of an enemy's equipment, the biological killing effect of the combatants should also be considered. This research includes the study of the damaging effects to sensitive target areas of brain tissues by acoustic weapons, 11 laser weapons, 12 high-explosive weapons, 5 and electromagnetic weapons; the study of the pattern and characteristics of the morphology, structure, function and development of the brain; and the study of establishing the relationship between weapon parameters and their killing effects. The analysis of brain damage can provide feedback to enhance the research and manufacture of weapons, and research on the injury target will promote the innovation and development of weapons, providing new theoretical support for future battlefields.…”

Military Brain Science is a cutting-edge innovative science that uses potential military application as the guidance. It was preliminarily divided into 9 aspects by authors: understanding the brain, protecting the brain, monitoring the brain, injuring the brain, interfering with the brain, repairing the brain, enhancing the brain, simulating the brain and arming the brain. In this review, we attempt to propose the concept, content and meaning of the Military Brain Science, with the hope to provide some enlightenment and understanding of the research area.

Abstracte rapid boom in technological advances during the 20 th century transformed the dream of further space exploration from a dream to stark reality. e hostile relations of the Cold War that spurred the so-called "space race" gave way to international cooperation in space investigation. However, the cooperative tone experienced over the past few decades is not entirely indicative of the global political landscape. International space relations are still developing, as is the international space law. Without any formal authority over the regulation of space ventures, the possibility of dissension remains. is paper explores the potential for international con ict over the resources, control, and even military presence in outer space. e United States' dominance as the acting authority over outer space enterprises will result in a great impact global politics in both the near and distant future.

“…Degradation in the spatial beam quality, for instance, is often a notorious signal indicating the onset of severe thermal effects in the laser gain medium that ultimately limit the power range. Mitigation of thermal and other nonlinear effects is currently the subject of major research efforts aimed at developing practical high power lasers, which are preferably electrically pumped and solid‐state and that address a range of large‐scale applications in areas such as particle acceleration, security and defense, clean energy and in space propulsion . The most prominent strategies used so far have involved drawing on the advantages obtained from the geometry of the active medium (slab, fibre, thin disk), by exploiting the enhanced material properties at cryogenic temperatures, and through combination of beams from multiple separate lasers.…”

Ever since the laser's invention, there has been great interest in increasing beam output power without detriment to its coherence. Despite great advances having been obtained through the use of a diverse range of approaches, steady‐state beam powers above ten kilowatts remain a significant challenge for solid‐state lasers due to the heightened impact of detrimental nonlinear effects such as thermal lensing. Multiplexing several lasers using beam combination represents a method for surpassing the power barriers of single lasers. Here we propose and demonstrate a novel approach to beam combination and power scaling based on Raman conversion in diamond. Power from multiple non‐collinear pump beams is efficiently transferred onto a single Stokes beam in a single‐pass amplifier. Using three mutually‐independent nanosecond pulsed beams from a free‐running‐linewidth 1064 nm laser, 69% of the total peak pump power of 6.7 kW was transferred onto a TEM00 Stokes seed pulse at 1240 nm in a 9.5 mm long diamond crystal. Compared to other beam combination techniques, diamond beam combination has advantages of relaxed constraints on pump beam mutual coherence, while enabling narrowband output. Thermal considerations for extending from low duty‐cycle to continuous wave operation and higher power levels are discussed.
