We sincerely invite students who are interested in photonics engineering and optoelectronic information engineering to apply for master degree. My research interests include fiber lasers, nonlinear and ultrafast optics. Fiber laser is a modern laser, whilst its high power and high stability is applicable to many practical fields. The nonlinear optics produce ultrafast laser pulse, which can produce very high peak power and are applicable for industrial processing fields such as laser cutting and laser direct writing. I have nearly 10 years of experience in the fields of fiber lasers, nonlinear and ultrafast optics. I published more than 10 articles in SCI-indexed Q1 in the past five years. In addition, I am proficient in both Chinese and English communication and writing. Students who are interested in applying for master degree are welcome to my office for further discussion.
