Yinglin Song received a PhD in Physics in 1994 from the Harbin Institute of Technology, where he worked on third-order nonlinear optics, optical limiting, and laser-induced damage of materials. He joined the physics department at the Harbin Institute of Technology in 1994 and earned the title of Professor and PhD supervisor in 1999 and 2000, respectively. He was awarded the Distinguished Young Scholars of Heilongjiang Province and Program for New Century Excellent Talents by the University Ministry of Education in 2004. His current research interests concern the characterization of the nonlinear optical properties of materials and the development of novel nonlinear optical measurement methods as well as the applications of these nonlinear materials/devices for optical switching, optical limiting, sensors, etc. He developed a variety of nonlinear optical measurement techniques such as an in situ 4f phase imaging method and single-shot transmittance measurement with phase object (T-PO). He has received six Provincial Science and Technology Awards. He has published ~300 papers in SCI journals and his paper citations are over 6000. He has been granted 30 patent licenses for inventions in China. He developed a series of nonlinear optical measurement devices, including a transient refraction spectrometer, in situ 4f phase imaging measurement devices, double-4f phase imaging measurement devices, all-in-one Z-scan measurement devices, etc.
