Optimization of temporal gate by two-color chirped lasers for the generation of isolated attosecond pulse in soft X rays被引量：4
《Photonics Research》2019年第12期1407-1415,共9页LIWEI HE GUANGLU YUAN KAN WANG WEIJIE HUA CHAO YU CHENG JIN 
National Natural Science Foundation of China(11774175,11704187,11774174,11834004)
We propose a simple and efficient method to optimize two-color chirped laser pulses by forming a"temporal gate"for the generation of isolated attosecond pulses(IAPs)in soft X rays.We show that the generation process f...

Effective suppression of stimulated Raman scattering in half 10 kW tandem pumping fiber lasers using chirped and tilted fiber Bragg gratings被引量：13
《Photonics Research》2019年第2期167-171,共5页MENG WANG ZEFENG WANG LE LIU QIHAO HU HU XIAO XIAOJUN XU 
National Natural Science Foundation of China(NSFC)(11274385)
The average power of fiber lasers has been scaled deeply into the kW regime in the past years. However, stimulated Raman scattering(SRS) is still a major factor limiting further power scaling. Here, we have demonstrat...
