On March 18, the result of Science and Technology Award, Shaanxi Academy of Sciences 2014 was revealed, the project“Theoretical and Technological Study Based on Dissipative Soliton New-Type Illuminant” under the charge of a researcher from State Key Laboratory of Transient Optics and Photonics, XIOPM was awarded the first prize.
The project“Theoretical and Technological Study Based on Dissipative Soliton New-Type Illuminant”, supported by National Natural Science Foundation of China, with dissipative soliton as study object, systematically studied multiple nonlinear optical phenomena of fiber lasers, and provided a new theory and method for application and research of fiber laser technology that of high energy and short-duration pulse. Its achievements are as follows:
1. It studied typical behavioral characteristics of dissipative soliton mode locked laser, and revealed formation mechanism, output characteristics and dynamic evolutionary rule of multiple dissipative soliton.
2. It systematically and deeply studied multiple nonlinear effects of fiber lasers and revealed a new theory and internal mechanism in the interaction between dissipative soliton and continuous wave as well as multiple dissipative soliton in fiber. Besides, it also provided a new theory and method for application and research of laser technology that of high energy and short-duration pulse.
3. It proposed a series of new nonlinearity/ dispersion management methods and technologies of whole-fiber-structured laser, discovered 2 fission pulses of high energy but no wave based on strong-nonlinearity and great dispersion laser system (separately are ultra-wideband high energy dissipative soliton and no-wave fission square wave dissipative soliton), which improved more than 3 magnitudes compared with the traditional soliton in respect of outputting pulse energy directly.
SCI has published 116 papers upon this project and cited 739 times. 8 representative papers was cited by SCI for 180 times; 3 papers were awarded “The Most Influential 100 International Academic Papers, China 2009-2011”; 1 elected to ESI Hot Paper; 3 elected to 1% Highly Cited Papers of ESI International Physics Field; 5 published on instrumental science periodicals with IF >7; 48 published on series periodicals with IF>3 and IEEE. In addition, 3 invention patents were authorized to the project. The main scientific value of the project lies on overcoming the negative impacts of nonlinear effect on optical pulse in laser system, obtaining multiple high energy no-wave fission dissipative soliton, establishing theoretical system based on mode locked dissipative soliton, expanding a new field for interaction between pulse and substance under the condition of strong-nonlinearity and high dispersion, and effectively promoting the application and development of dissipative soliton in high energy and short-duration laser technology. Its study achievements were regarded as typical illustrative examples of dissipative soliton and have been cited and commented by leading experts at home and abroad for many a time. For example, N. Akhmediev, an international famous nonlinear optical theory expert and Australian National University professor, in his/her comprehensive article published on Nature Photonics, deemed that the project verified the resonance theory of dissipative soliton in the experiment for the first time; professor K. P. Loh, who has published several Nature papers, cited the study results of the project many times and pointed that “the fact dissipative soliton energy is much greater than traditional soliton has been certified by the project”. Research team of Wang Qingyue, a Chinese famous ultrafast expert and professor of Tianjin University, cited the study results of the project in many papers and regarded the dissipative soliton as a example of “the newly proposed mode locked technology”; professor A. Zaviyalov from Friedrich-Schiller-Universit?t Jena held the opinion that the dissipative soliton oscillator put forward in the project is able to realize output of giant chirped pulse; research team of P. P. Shum, an IEEE senior member and professor of Nanyang Technological University, Singapore stated that the project laser possesses advantages of compact structure and whole-fiber-structure. Relevant papers of this project were also cited in monograph Laser System For Applications and deemed that the project has important significance on development of controlled super-continuum spectrum produced in laser.
