A High-Efficient Switchable Third Harmonic Source Developed by ITMO Researchers
A team of scientists from ITMO University have developed a record-thin device that decreases the wavelength of a laser beam by threefold. The process, known as the third harmonic generation, is now more efficient thanks to a 20 nm-thick film made of chalcogenide alloys that generates radiation in a wide range of wavelengths without amplification by nanoresonators and performs 100-1,000 times better than similar devices. The technology will be useful in further research related to tissues and cells in laser scanning microscopes and signal processing in photonic integrated circuits for quantum communication. The corresponding article is published in Laser & Photonics Reviews.

ITMO Researchers Suggest Model to Predict Parameters of Laser Metal Transfer Onto Glass
Scientists from ITMO University have developed a physical and mathematical model to predict the parameters of laser metal ablation onto a transparent substrate. Apart from providing a detailed model of the physical process, the new tool can predict its key parameters with a 90% accuracy. This opens up possibilities for the controlled creation of metallic coatings with micron-level resolution on glass, such as indelible protective marks and decorative elements. The results of this Russian Science Foundation-supported study were published in International Journal of Heat and Mass Transfer.

Butterfly Effect: ITMO Researchers Create Colorful Perovskite Films for Optoelectronics
Scientists from ITMO have developed a new method for creating colorful structured semiconductor perovskite films without the risk of defects or contamination. A special nanopattern that imbues perovskites with optical properties is applied with a laser not onto the perovskite film itself but onto a titanium dioxide substrate. The resulting films can be used to change the direction of luminescence. With such nanostructured semiconductors, it’s possible to develop a new type of solar cells and diodes with improved electrophysical characteristics. The study is described in a paper published in Light: Advanced Manufacturing.

Lasers for Medicine: ITMO Alumna’s Startup Aims to Improve Cancer Treatment
After studying laser technology at ITMO, Iulia Ruzankina applied her skills in the fields of metal processing and mineral resources. Everything changed when she lost her father to cancer – from then on, she decided to devote herself to improving cancer treatments. Today, her team is working on a photonic endoscope that could provide a minimally invasive way to destroy tumors without harming healthy tissue. With the prototype ready, the startup team is planning to conduct animal and then clinical trials. ITMO.NEWS spoke to Yulia about her path as a researcher and the role of lasers in medicine.

A Novel Atom-Twisting Method Proposed by ITMO Researchers
Scientists from ITMO University discovered that an atom adopts a twisted structure when absorbing twisted light. As the proposed model facilitates and accelerates the twisting process, it provides an insight into the physics of interactions between structured light and complex quantum systems, as well as will be helpful in microscopy, quantum tomography and computing, and telecommunications. The results of the study are published in Physical Review. The research is supported by the Russian Science Foundation.
