Effects of Temperature and Buffer Gas Pressure on Single Photon Degenerate Four-wave Mixing

Sun Jiang

In order to study the Rydberg state of Barium atom,single photon resonant degenerate four-wave mixing(FWM)was used to measure the 6s6p1P1 energy level of Barium atom,and FWM specture signal under different experimental conditions were achieved.The results showed that the influence of temperature and laser intensity on FWM are relatively obvious but the buffer gas pressure is relatively poor.These results may serve as a useful reference in further research work on the Rydberg state of Barium atom.

[Optics heterodyne detection of the autoionization state of barium].

Jiang Sun, Hongxin Su, Yan-bang Wang +3 more

The autoionization state of barium was observed by optics heterodyne between three-photon resonant nondegenerated six-wave mixing (NSWM) and two-photon resonant nondegenerated four-wave mixing (NFWM). In this way, optics heterodyne spectrum of 6p(3/2) 19d autoionization state of barium was measured. The suppression and enhancement of the NFWM signal was observed which was caused by the quantum interference between NFWM and NSWM. Our method is a pure nonlinear optic technique. It has the advantages of excellent spatial signal resolution and simple optical alignment. Here two-photon resonant NFWM is used as local oscillation, while three-photon resonant NSWM signal is used as signal beam. Detection of autoionization states of Ba was achieved by changing the frequency of signal beam. The phase matching condition of this technique is not so stringent and can be achieved over a very wide frequency range, which is very difficult in the general six-wave mixing. Furthermore, the signal is coherent light. Optics heterodyne spectrum is a Doppler-free spectroscopy when the incident lasers have narrow bandwidths.
