Intensity correlation in frequency upconversion via four-wave mixing in rubidium vapor

We report a study on the transfer of intensity correlation properties in frequency upconversion via four-wave mixing (FWM) in rubidium (Rb) vapor. The 5S1/2−5P3/2−5D5/2 two-photon transition in Rb85 leads to collimated blue light (CBL) generation at 420 nm by absorbing two input photons of wavelengths 780 nm and 776 nm. The g(2)(τ) intensity correlation measurement of the CBL field reveals that the intensity correlations of the input fields are transferred to the CBL field due to strong atomic coherence in the FWM loop. We also demonstrate that the measured values of g(2)(τ) of the CBL field are reduced by the effect of Doppler broadening of Rb vapor.We report a study on the transfer of intensity correlation properties in frequency upconversion via four-wave mixing (FWM) in rubidium (Rb) vapor.

Unusual resonance effect of flourescence emitting from sinters of rare-earth-oxide Er2O3 and some inorganic oxides

Zhengwei Liu, Jian Liu, Zhezhao Zeng

We report for the first time that energy upconversion occurs when the same material was excited by monochrome light of different wavelength. The TTQLL (Three Times Quantum Liquid Law) Fermi Resonance Fluorescence Law advanced by the author in reference 1 is further proved, that is, the peak value of the excited fluorescence posses the following relationships with the wavelength of the excitation light: (lambda) 0/4, (lambda) 0/3, (lambda) 0/2, 2(lambda) 0/3, 3(lambda) 0/4, (lambda) 0, 5(lambda) 0/4, 4(lambda) 0/3, 3(lambda) 0/2, 2(lambda) 0, 3(lambda) 0. We also further discussed the radiation mechanism of this fluorescence and provided a theory model.We report for the first time that energy upconversion occurs when the same material was excited by monochrome light of different wavelength.
