FEFU Scientists Created The Nanostructure Ultrafast Laser Printing Technology

Scientists of Far Eastern Federal University (FEFU), in collaboration with Russian and foreign colleagues, have developed a technology of nanostructure ultrafast laser printing. The new method allows creating nanoscale structures on the surface of metals using a femtosecond laser with a frequency of one million pulses per second. To achieve this, the scientists split each beam into 50 pulses with the help of special optical elements. This technology will be useful for quick and economical creation of touch devices for solving various tasks.

Employees of the FEFU School of Natural Sciences and School of Engineering, the Far Eastern Branch of the Russian Academy of Sciences, research centers of Moscow, St. Petersburg and Samara, as well as scientists from Australia and Spain took part in the technology development. The experiment results are published in Scientific Reports, Applied Surface Science and Optics Letters.

Currently, Far Eastern Federal University is conducting a series of studies on laser printing technology using various methods. Scientists can conduct various experiments in this area owing to a recently installed laser lithograph, one of the best in Russia. Thus, a group of university researchers together with colleagues published about a dozen articles in international journals in this area.
