Scientists from the Moscow Institute of Physics and Technology, located in Dolgoprudny, and other research institutions have developed an innovative method for self-assembling carbon nanotubes, which allows creating films with an ordered arrangement. They increase the efficiency of lasers generating ultrashort light pulses by 30%. These lasers are used in biology and medicine to obtain high-quality images of tissues and organs, which helps in the diagnosis of diseases, including oncology.
We expect that our results will help improve the quality of fiber lasers and thereby expand their application in science, industry, and medicine.
Ultrashort pulses, lasting a quadrillionth of a second, are necessary for high-precision "photography" of biological processes, which is especially important in medicine for diagnosing diseases. However, traditional lasers often suffer from noise that distorts signals. Ordered nanotubes polarize light, which improves the characteristics of laser pulses.
The material developed by scientists can be used in long-term studies, such as the diagnosis of oncological diseases, and has already formed the basis of a new laser system for dermatology. The research is supported by grants from the Russian Science Foundation, which emphasizes its importance to the scientific community.
The work on improving medical lasers was carried out by researchers from the Moscow Institute of Physics and Technology (Dolgoprudny), the A. M. Prokhorov General Physics Institute of the Russian Academy of Sciences (Moscow), and the N. E. Bauman Moscow State Technical University.
