Research Areas:

Lv Xinjie’s research focuses on all-solid-state lasers, fiber lasers and nonlinear frequency conversion as well as the engineering of these devices.

Lv has taken charge of or played a major part in a number of projects of the National Natural Science Foundation of China, the 863 Program, special projects on international cooperation and major research instruments.

He has developed several sets of mid-infrared laser devices, with tunable output wavelengths of 1.5um-4.3um, continuous output wavelengths of 10W@3.1um, nanosecond pulse of 30W@2.0um and a picosecond pulse of 3W@3.2um. The beam quality, power stability and non-failure operation time of the above prototype devices have all reached the quality of commercial laser devices. They have been on display at “LASER-World of Photonics 2019,” Munich, and “2019 the 17th China International Exhibition of Scientific Instruments and Laboratory Equipment,” Beijing. They have also been tried out and purchased by Anhui Institute of Optics and Fine Mechanics (AIOFM) of Chinese Academy of Sciences (CAS), Electronic Engineering Institute of PLA, and Shanghai Institute of Technical Physics of CAS.

Profile:

Lv Xinjie graduated in 1999 from Hebei Zhengding High School, earned his bachelor’s in 2004 from the Department of Physics, University of Science and Technology of China and his MS in 2007 from the Research Center of Laser Fusion of China Academy of Engineering Physics. Lv then pursued his doctoral studies at the School of Physics, Nanjing University (NJU), obtained the doctorate in 2010 and continued post-doctoral research at the College of Engineering and Applied Sciences, NJU, between 2010 and 2012. He then worked as an associate researcher at NJU’s College of Engineering and Applied Sciences, and in 2014, he became a senior engineer there.
