Indian scientists have developed a new type of laser pointer material: greatly improving the efficiency of solar power generation. Scientists from the Indian Institute of Science and Technology have designed a new type of laser material that can change the way solar energy is obtained, thereby making solar power generation more efficient.
The professor and his team in the solid-state and institutional chemistry department of his university designed a nanocrystalline material that can emit a convergent beam with a smaller amount of light than ordinary lasers. According to existing records, this material requires only minimal energy to excite the laser. The professor said: “Therefore, it can convert extremely low-energy light into a laser beam.”
At the same time, this material can also absorb wide-band light, which also means that it is possible to convert light into a laser beam in the future, the professor added. One potential application of this discovery is in the field of solar power generation. This material can absorb more light from the light source, such as sunlight, and emit a beam of light in a specific direction. The ability to absorb light in a specific direction makes this material easier to apply to the field of solar cells.
3D laser direct writing technology is expected to create a new era of micro-nano optics. A research team from the University of Stuttgart in Germany said recently that they have been able to 3D print more accurate and reproducible micron-level optical devices. This research breakthrough will have a great impact on the production of micron-level integrated optical components, and will also achieve further miniaturization of devices required for sensing or communication applications.
A research team led by the director of the Ultrafast Nano-Optics Laboratory of the Department of Physics, University of Stuttgart, Germany, demonstrated how to construct optical devices as small as 4.4 microns through the “femtosecond green laser pointer direct writing” technology. The study shows that 3D printed micron-level optical devices are almost very close to the results of digital simulation.
Although the femtosecond laser direct writing technology is still in the laboratory research and development stage, we have proven that highly repeatable and reliable high-performance micro-optical devices can be fabricated through this technology. We believe that our research methods can be further expanded for mass production and used for direct printing of any type of small-scale optical devices, creating a new era of integrated micro-optics and nano-optics.
