• Russian and Dutch Researchers on What’s Holding Back a Revolution in Data Storage

  Almost all of us store data on cloud services and use social networks. Some know that servers hosting that data occupy whole buildings and require significant resources to maintain. The world’s best researchers are at work trying to make data hosting more affordable, secure and user-friendly, but no revolutionizing changes have happened so far. Recently, Alexandra Kalashnikova, a physicist at the Ioffe Institute and ITMO University, along with colleagues from Radboud University Nijmegen (the Netherlands) and the Prokhorov General Physics Institute of the Russian Academy of Sciences have published a paper in Physics Reports. In the article, researchers explain why the industry hasn’t yet begun recording data on HDDs with lasers, or dropped disk drives altogether. Alexandra told ITMO.NEWS more about the paper.

• ITMO University PhD Student Evgeniy Odlyanitskiy on Creating a Laser Facility During Isolation

  Last year, Evgeniy Odlyanitskiy, ITMO University Faculty of Photonics and Optical Information’s PhD student, was invited for a six-month long internship at the University of Bordeaux in France. In six months, the Russian-French research team was supposed to create a laser system that is able to take high-quality pictures of objects in terahertz frequency range with subwave resolution. At the moment, the only system of that kind is located in Japan. Evgeniy was supposed to create his own version to be applied in the field of biophotonics. Read on to learn more about his research process and achieved results in this ITMO.NEWS article.

• Scientists from ITMO and S.N. Fyodorov Eye Microsurgery Complex Have Developed and Introduced New Laser Method for Cataract Surgery

  Cataract is among the most widespread eye diseases. According to WHO, up to a third of all visual impairments have to do with cataract. The treatment methods are well-known but can sometimes be traumatizing. Scientists from ITMO and the S.N. Fyodorov Eye Microsurgery Complex spent over 20 years working on reducing the side effects of cataract surgery. As a result, they came up with a technology where a laser is used both to destroy the clouded eye lens and to stimulate the regeneration of adjacent tissue. The researchers gave a detailed description of their method in an article that has been recently published in Optical and Quantum Electronics.

• ITMO University Scientists Develop Laser for High-Precision Satellite Navigation

  Scientists from ITMO University’s Research Institute of Laser Physics have developed a high-power laser with short pulse duration for use in a lunar laser locator. The locator will make it possible to measure the distance between the Moon and Earth with a margin of error of just a few millimeters. This would make it possible to correct calculations of celestial coordinates of the Moon in order to improve the accuracy of satellite navigation systems. An article on the new laser was published in Optics Letters.

• Holographic Quantum Dot Laser in Progress

  How can we make a laser that will work effectively on low pump energy, be quite small and will allow dynamically changing the output radiation spectrum?  Vladimir Borisov, a  PhD  student at ITMO’s Department of Photonics and Optical Information Technologies, has won a grant of the Russian Foundation for Basic Research for creating just such a laser. One of the advantages of the new device is that the resonator is placed in the active laser medium, which simplifies the design while changing the resonator itself; it is created by  holographic  grating and uses quantum dots as photon sources.

• Lasers&Photonics Congress: Quantum Dots and Topological Insulators

  The 18th Lasers&Photonics Congress has just kicked off in St. Petersburg; it includes several conferences, schools for young scientists and students, and an exhibition on laser and optoelectronic technologies. The main topics of the congress are: research into quantum dots and their practical application in lasers, a new concept of lasers based on topological insulators, as well as the possibilities offered by the European X-ray free-electron laser (XFEL), experiments on which began last autumn. These topics were discussed during the plenary presentations by the event’s main speakers. The congress is organized by ITMO University together with its partners.

• Scientists Propose New Type Of Terahertz Solid-State Laser

  A team of scientists from ITMO and Vladimir State University have proposed a new type of a solid-state terahertz laser. According to their research, such laser will be more efficient compared to existing devices, as well as allow stepless frequency tuning. In future, the proposed model which is based on the use of gallium-nitride quantum dots can lay the groundwork to creating a compact solid-state source of terahertz radiation that can be effectively applied in medicine, security systems, and other fields. The results were first published in ACS Photonics journal, and a separate review of the research was included in Nature’s “News and Views”.
