Russia expects to make substantial breakthroughs in laser pointers and electromagnetic weapons

Russian Deputy Minister of Defense Yuri Borisov said in a meeting with the academician of the Russian Academy of Sciences that the Russian Ministry of Defense hopes to make substantial breakthroughs in the development of laser pointer and electromagnetic weapons. He said that the cooperation between the Russian Academy of Sciences and the Ministry of National Defense has several specific goals. The first is the research and development of scientific and technological reserves, and he especially hopes to achieve substantial breakthroughs in laser and electromagnetic weapons. Significant efforts must be made to supplement the scientific research foundation so that military science can create entirely new weapons and equipment.

In September of last year, Yuri Borisov stated that certain laser weapons, namely air and ground systems, have been installed in Russia. In 2013, Russian President Putin stated that the research and development of laser weapons is a very promising direction in the field of scientific research in Russia. Researchers have discovered new crystal structures that are expected to be used in lasers. A research team from Florida State University has discovered a new crystal structure of organic-inorganic hybrid materials, which may realize new applications in photoelectric devices such as light-emitting diodes and lasers.

The results of this study were published in the journal Nature Communications. Associate Professor of Chemical and Biomedical Engineering has been studying a class of crystalline materials called metal halide perovskites for the manufacture of high-performance optoelectronic devices for the past few years. In recent work, his team assembled organic and inorganic components to form a one-dimensional structure.

The basic structural unit of this type of material is the same, just like a Lego brick, you can use it to assemble into different structures, these modules like Lego bricks, scientifically called metal halide octahedron, can form three-dimensional Network, two-dimensional layered, or even one-dimensional chain structure. Three-dimensional and two-dimensional structures have been extensively studied, but there are few studies on one-dimensional structures. The research team found a way to put these fragments on a chain, and then the chain was wrapped with organic components to form a core fiber-clad structure. Then millions of such organic coated wires are stacked together to form a crystal beam. From a distance, these structures look like crystal needles.

This is the first time scientists have observed that these mixed materials form a crystal structure like this. This crystal shows very interesting optical properties. For example, it can be highly photoluminescent, so scientists can manipulate it according to its application in different technologies. In recent years, mixed metal halide perovskites have received increasing attention due to their potential applications in various types of photonics-related technologies such as photovoltaic cells, light-emitting diodes, and green laser pointer. By showing that this one-dimensional structure may be another effective form of generating bright light, this new research takes this work one step further. They are good light emitters. This research tells us that we have the ability to develop new structures. These materials have great opportunities to be used in practical applications such as LEDs or laser devices.
