Diffuse Laser Cooling Based on the Excited State of Rubidium Atoms via 420 nm Blue Light
Jia Zhang, Xun Gao Zheng Xiao, Xiaolei Guan Ruihang Chen +2
To date, the laser cooling of rubidium atoms has inevitably relied on 780 nm cooling light corresponding to the first excited state . Surprisingly, we demonstrat…
Active optical clock based on four-level quantum system
Tonggang Zhang, Yanfei Wang, Xiaorun Zang +2
Active optical clock, a new conception of atomic clock, has been proposed recently. In this report, we propose a scheme of active optical clock based on four-level quantum system.…
Magic wavelengths for lattice trapped Rubidium four-level active optical clock
Xiaorun Zang, Tonggang Zhang, Jingbiao Chen
After pumped from ground state to state, the population inversion between and will be established for Rubidium four-level active opt…
Active Ion Optical Clock
Wei Zhuang, Tonggang Zhang, Jingbiao Chen
In this paper, we propose a scheme of active ion optical clock with detailed pumping method, lasing states, output power, linewidth and light shift. Using 171Yb+ ions in a Paul Tra…
