In the future, this discovery will be helpful in the development of new technologies for wireless transfer of energy and data. The research was carried out by scientists from ITMO University and Moscow Institute of Physics and Technology (MIPT). The paper was published in Laser & Photonics Reviews.
With this non-paint brush of over 20 colors and shades, artists may no longer need to be afraid of uneven lines or inadequate palettes. All missteps can be easily erased or repainted with no risk of ruining a picture. The first prototype of the laser brush should see the light of day by the end of summer. In the meantime, the researchers have published an article describing the very technology of laser miniature painting on metallic surfaces.
For six years, a research team from the Photophysics of Surface Laboratory at ITMO’s International Research and Educational Center for Physics of Nanostructures has been studying plasmonic nanolasers – a long-standing subject of debate in the scientific community. The study was conducted as part of a Russian Presidential Grant.
Andrei Gorodetsky received his PhD degree at ITMO’s Faculty of Photonics and Optical Information in 2010. Now, he works at the University of Birmingham and continues to supervise projects at ITMO University.
Modern computers are becoming increasingly more power-hungry and their performance doesn’t always meet our needs. Some say that optical computers could be the solution. ITMO University professor Ivan Iorsh spoke to ITMO.NEWS to help us learn what they are.
This effect can be used to control the internal stress on surfaces of transparent objects, which is required to monitor quality control of products and their technical state.
The results of this research can be used to control the properties of light and matter and to create quantum memory.
This will potentially allow them to create more compact and efficient elements for lasers, sensors, and optical chips. Moreover, it proves the hypothesis that ITMO physicists had about the connection between a material’s refractive index and its electronic features. The research has been published in Nanophotonics.
The scientists will develop a method for the development of waveguides invisible to the naked eye and which will make it possible to transmit images onto transparent glass and polymer surfaces. It will also be possible to use the same technology to create sensors useful in the production of protective eyewear for workers in hazardous occupations.
The effect that can be seen on the picture is called photoluminescence. Quantum dots made out of cesium perovskite receive ultraviolet light that gets absorbed by quantum dots and then re-emitted, but in the spectral range.
