An ultra-stable cryogenic sapphire cavity laser with an instability of based on a low vibration level cryostat
Leilei He, Jingxuan Zhang, Zhiyuan Wang +4
Cryogenic ultra-stable lasers have extremely low thermal noise limits and frequency drifts, but they are more seriously affected by vibration noise from cryostats. Main material ca…
3 m3 m heterolithic passive resonant gyroscope with cavity length stabilization
Fenglei Zhang, Kui Liu, Zongyang Li +9
Large-scale high sensitivity laser gyroscopes have important applications for ground-based and space-based gravitational wave detection. We report on the development of a 3 m$\time…
All-optical frequency resolved optical gating for isolated attosecond pulse reconstruction
Zhen Yang, Wei Cao, Xi Chen +7
We demonstrate an all-optical approach for precise characterization of attosecond extreme ultraviolet pulses. Isolated attosecond pulse is produced from high order harmonics using…
A hybrid silicon-sapphire cryogenic Fabry-Perot cavity using hydroxide catalysis bonding
Yun-Long Sun, Yan-Xia Ye, Xiao-Hui Shi +5
The third-generation gravitational wave detectors are under development by operating the detector in cryogenic temperature to reduce the thermal noise. Silicon and sapphire are pro…
Suppression of residual amplitude modulation effect in the Pound-Drever-Hall locking
Xiaohui Shi, Jie Zhang, Xiaoyi Zeng +4
Residual amplitude modulation (RAM) effect in a Pound-Drever-Hall (PDH) technique locked cavity system is analysed in this paper. Frequency shift caused by RAM in PDH is found to b…
Direct laser cooling Al+ ions optical clocks
J. Zhang, K. Deng, J. Luo +1
Al ions optical clock is a very promising optical frequency standard candidate due to its extremely small blackbody radiation shift. It has been successfully demonstrated with…
Design of an optical reference cavity with low thermal noise and flexible thermal expansion properties
J. Zhang, Y. X. Luo, B. Ouyang +3
An ultrastable optical reference cavity with re-entrant fused silica mirrors and a ULE spacer structure is designed through finite element analysis. The designed cavity has a low t…
