Based on the density matrix equations with 3-j symbol expression, we calculated the intensities and lineshapes of fluoresence signals for two-photon transitions between homonuclear diatomio molecular singlet electronic states, which have a near-resonant intermediate enhancing level.

Based on the density matrix equations with 3-j symbol expression, we calculated the intensities and lineshapes of fluoresence signals for two-photon transitions between homonuclear diatomio molecular singlet electronic states, which have a near-resonant intermediate enhancing level. Calculations were made for interactions between a variety of polarization modulated laser fields with three level systems. Signals obtained by the phase-sensitive detection method showed that either the circular polarization modulated two-photon speotroscopy (GPMTPS) or the linear polarization modulated method (LPMTPS) could be used to eliminate the Doppler broadening background caused by the adsorption of two photons from one beam. In addition these methods could be used to identify the specific branches of the two-photon lines from their irreguler spectral structures without the need of knowing the upper level constants. Signal ratios of equal-frequency two-photon transitions under circular polarization modulation condition to those with linear polarization modulation were listed for all the branches with ΔJ= ±2, ±1 and 0. Differences of the results might be orders of magnitude for a resonable large J value. On the other hand signal ratios of two-photon branches in the intensity modulated circular polarization laser field to those in linear polarization fields (shown in another list) are all in the same order. Furthermore, a table is presented to show the relative signal intensities of unequal-frequency polarization modulated two-photon transitions between various electronic states. It might be useful for determining intermediate or upper electronic states of a resolved two-photon absorption line. PMTPS is thus expected to be a useful method for molecular spectroscopy or highresolution laser speotroscopy.

本文从密度矩阵运动方程出发,推导出当各种不同偏振调制激光场与三能级粒子系统相互作用时,同核双原子分(具近共振中间能波)单重电子态之间的双光子跃迁所产生的荧光信号强度和线型.对比偏振调制的与光子强调制的信号强度和线型时,表明:偏振调制双光子光谱(PMTPS)不仅能消除由吸收同一光束的同向双光子所产生的多普勒加宽背景,极大地提高光谱分辨率;而且不同电子态之间跃迁的O、P、Q、R、S支谱线强度与激光偏振状态有关,可借以标识分子的高激发电子终态和转动能级,有选择地简化复杂的分子光谱.可以预期,PMTPS是研究分子光谱和高分辨率激光光谱极有用的一种技术.
