Real-time suppression of random phase drift for laser ranging with high-frequency intermode beats
《Chinese Optics Letters》2023年第4期21-25,共5页杨睿韬 孙昊 胡鹏程 杨宏兴 付海金 于亮 邢旭 丁雪梅 谭久彬 
supported by the National Natural Science Foundation of China(NSFC)(Nos.52175501 and 51605120);the Heilongjiang Provincial Natural Science Foundation(No.LH2021E059);the National Key Research and Development Program of China(No.2020YFC2200204)。
Laser ranging with frequency comb intermode beats[IMBs]has been suffering from random phase drifts[RPDs]for two decades.In this study,we reveal the influence of signal transmission path on the RPDs and propose a real-...

Impact of external optical feedback on the beat notes of dual-polarization fiber lasers
《Chinese Optics Letters》2017年第7期22-26,共5页余贶琭 程凌浩 劳奕琴 李云波 关柏鸥 吴重庆 赵耀 
supported by the National Natural Science Foundation of China(Nos.11474133,61235005,61210006,and61275075);the Guangdong Natural Science Foundation(No.S2013030013302);the BJTU Fundamental Research Funds(No.2014RC016)
We present a theoretical analysis and an experimental study of the impacts of external optical feedback on dualfrequency fiber lasers. The external optical feedback can effectively suppress the phase noise of the beat...

Beat note analysis and spectral modulation of terahertz quantum cascade lasers with radio frequency injection
《Chinese Optics Letters》2017年第1期95-99,共5页朱永浩 黎华 万文坚 顾立 周涛 Stefano Barbieri 曹俊诚 
supported by the“Hundred-Talent”Program of Chinese Academy of Sciences;the National Natural Science Foundation of China(No.61575214);the Shanghai Municipal Commission of Science and Technology(Nos.14530711300,15560722000,and 15ZR1447500);the National 973 Program of China(No.2014CB339803);the Major National Development Project of Scientific Instrument and Equipment(No.2011YQ150021)
We demonstrate the electrical beat note analysis and radio frequency （RF） injection locking of a continuous wave （cw） terahertz quantum cascade laser （QCL） emitting around 3 THz （-100 μm）. In free running the...
