Prof. Yury Andreev visited the school of information science and engineering, Shandong University from October 16, 2011 to October 19, 2011.
Yury Andreev was born in Tomsk/Russia in 1946. He received the diploma degree in quantum electronics from Tomsk State University, Tomsk/Russia in 1972, PhD degree in physics and mathematics from Tomsk State University in 1988 and post doctor of science degree in 2000. In 2000 he joined the Institute of Climatic and Ecological Systems SB RAS where he is as a chief scientist on current time. Since 1972 his principle research interests have been in the field of photon counting systems, mid-IR lasers and parametric frequency converters, gas analysis lidars and force optics systems. Last decade he is enjoined in fs pulse parametric frequency conversion and THz generation/detection. His contributions have led to well over 150 contributed papers in (open) refereed journals, two monographers and 7 author certificates.
During the visiting, Prof. Yury Andreev made a wonderful report titled “Physical properties and application of modified GaSe crystals”. Prof. Yury Andreev introduced the physical and optical properties of the ZGP, GaSe crystals and their applications in generating mid-infrared and THz lasers. Then he patiently answered the questions and discussed with the teachers and students. Laser sources in mid-infrared band have important applications in lidar, laser ranging, environmental monitoring, medicals, spectroscopy, and so on. Owing to lack of widely available solid-state lasers, optical parametric oscillator (OPO) has attracted much attention as an effective technique for radiation generations in this band. Terahertz waves have important applications in astronomy, atmosphere, high-resolution spectroscopy, plasma diagnostics, spectroscopic imaging, pharmaceutical industry, broadband wireless communication, and so on.
