论文摘要
已经根据梯子型（852 nm + 698 nm）三级CS系统（6S1/2-6p3/2-6p3/2-7d5/2）和房间定型的Cellomic cellomic callomic callomic voror进行了实验研究，已根据梯子型（852 nm + 698 nm）的三级CS系统（852 nm + 698 nm）进行了实验研究。通过扫描698 nm耦合激光器的频率，通过锁定的852-NM Probe Laser的透射增强，已证明了无多普勒高分辨率高分辨率电磁诱导的透明度（EIT）辅助双谐波光泵（Drop）光谱。使用EIT辅助的滴光谱来研究具有室温纤维纤维原子蒸气电池的CS 7D5/2激发态的高精细分裂间隔，以及用于提高频率级别频率的频率校准的频率校准，以提高频率级别的频率，并引入了波导型电型电型相调节器（EOPM）的射频调节侧带。 EIT的存在使降落光谱线宽更窄，并且可以显着提高光谱分辨率非常有帮助。受益于较高的信噪比（SNR）以及EIT辅助下降光谱的更好分辨率，在（f“ = 6），（f” = 5）和（f“ = 5）和（f” = 4）之间的超精细分裂间隔（cesium 7d5/2状态）（HFS6“ -5” -5“ -5” -5“ -5” = -10.60（0.160（0.160））已经测量了-8.54（0.15）MHz），因此，磁性 - 偶极性超细交流常数（a = -1.70（0.03）MHz）和电量符超细相互作用常数（b = -0.77（0.77（0.77）），用于CS 7D/2的contants contants contants contants contants contants contants。基本物理常数。
The measurement of Cesium (Cs) 7D5/2 excited state's hyperfine splitting intervals and hyperfine-interaction constants has been experimentally investigated based on ladder-type (852 nm + 698 nm) three-level Cs system (6S1/2 - 6P3/2 - 7D5/2) with room-temperature Cs atomic vapor cell. By scanning the 698-nm coupling laser's frequency, the Doppler-free high-resolution electromagnetically-induced transparency (EIT) assisted double-resonance optical pumping (DROP) spectra have been demonstrated via transmission enhancement of the locked 852-nm probe laser. The EIT-assisted DROP spectra are employed to study the hyperfine splitting intervals for the Cs 7D5/2 excited state with a room-temperature cesium atomic vapor cell, and the radio-frequency modulation sideband of a waveguide-type electro-optic phase modulator(EOPM) is introduced for frequency calibration to improve the accuracy of frequency interval measurement. The existence of EIT makes the DROP spectral linewidth much narrower, and it is very helpful to improve the spectroscopic resolution significantly. Benefiting from the higher signal-to-noise ratio (SNR) and much better resolution of the EIT-assisted DROP spectra, the hyperfine splitting intervals between the hyperfine folds of (F" = 6), (F" = 5), and (F" = 4) of cesium 7D5/2 state (HFS6"-5" = -10.60(0.17) MHz and HFS5"-4" = -8.54(0.15) MHz) have been measured, and therefore the magnetic-dipole hyperfine-interaction constant (A = -1.70(0.03) MHz) and the electric-quadrupole hyperfine-interaction constant (B = -0.77(0.58) MHz) have been derived for the Cs 7D5/2 state. These constants have important reference value for the improvement of precise measurement and determination of basic physical constants.
