摘要

实验证明,通过波长为7801367和743nm的激光辐射,在光学偶极阱(ODT)中的单个铷原子被三光子激光激发到37P里德伯态。通过光学方法利用ODT中原子的损耗来检测对里德伯态的激发。记录了ODT中单个里德伯原子的激光激发光谱,并测量了激发概率与激光脉冲持续时间的关系。测量的频谱宽度为2MHz。还对磁光阱中冷原子云在三光子激光激发原子到里德伯态过程中的荧光猝灭光谱进行了实验。将实验结果与数值计算结果进行了比较。考虑了提高ODT中里德伯原子相干三光子激光激发精度的方法。

Three-Photon Laser Excitation of Single Rydberg Rubidium Atoms in an Optical Dipole Trap

Three-Photon Laser Excitation of Single Rydberg Rubidium Atoms in an Optical Dipole Trap

Three-photon laser excitation of single rubidium atoms in an optical dipole trap (ODT) into the 37P Rydberg state by laser radiation with wavelengths of 780, 1367, and 743 nm has been experimentally demonstrated. The excitation to Rydberg states is detected by an optical method using the losses of atoms in the ODT. The laser excitation spectra of single Rydberg atoms in the ODT are recorded, and the dependence of the excitation probability on the laser pulse duration is measured. The measured spectrum width was 2 MHz. Experiments on fluorescence quenching spectroscopy of a cloud of cold atoms in a magneto-optical trap during the three-photon laser excitation of atoms to Rydberg states are also carried out. The experimental results are compared with a numerical calculation. Methods for increasing the accuracy of the coherent three-photon laser excitation of Rydberg atoms in the ODT are considered.
