The study of structured laser beams has been one of the most active fields of research for decades, particularly in exploring laser beams with orbital angular momentum. The direct generation of structured beams from laser resonators is deeply associated with the formation of transverse modes. The wave representations of transverse modes of spherical cavities are usually categorized into hermite–Gaussian(hG) and Laguerre–Gaussian(LG)modes for a long time. Enormous experimental results have revealed that the generalized representation for the transverse modes is the hermite–LG(hLG) modes. We make a detailed overview for the theoretical description of the hLG modes from the representation of the spectral unitary group of order 2 in the Jordan–Schwinger ***, we overview how to derive the integral formula for the elliptical modes based on the Gaussian wave-packet state and the inverse Fourier transform. The relationship between the hLG modes and elliptical modes is linked by the quantum Fourier transform. The most striking result is that the hLG modes can be exactly derived as the superposition of the elliptical modes without involving hermite and Laguerre ***, we discuss the application of the hLG modes in characterizing the propagation evolution of the vortex structures of hG beams transformed by an astigmatic mode converter. This overview certainly provides not only a novel formula for transverse modes, but also a pedagogical insight into quantum physics.

STUDIESOF MOLEcULAR REORIENTATION OF A NON-SPhERIcAL MOLEcULE IN ThE LIQUID STATE BY DEPOLARIZED RAYLEIGh ScATTERING

第33届中国气象学会年会

作者： T.T.hu D.Wu c.h.wang KeyLaboratoryofAridclimatechangeandDisasterReductionofGansuProvince CollegeofAtmosphereScienceLanzhouUniversity

South Asia high（SAh） and subtropical jet（SJ） are crucial weather systems in East Asian. SAh is also one of the important members of Asia summer monsoon system in upper troposphere, the East Asia subtropical westerly jet（EASWJ） located on the north and tropical easterly jet（TEJ） located on the south. This study highlights the interactions of them through the composite analysis of anomalous geopotential height（GPh）, heat flux and momentum flux events using reanalysis data. The intraseasonal variability of heat flux and momentum flux in both SAh and TEJ is dominated by linear interference. While the nonlinear interference plays an important role, especially in momentum flux propagating in EASWJ. The SAh can be divided into two parts: Tibetan high（Th） and Iranian high（Ih）. The property of stationary heat flux in these two parts is different. The heat flux propagating in SAh enhances when the center of SAh moves westward. The strength of TEJ and EASWJ enhance after the equatorward heat flux from Th and poleward heat flux from Ih *** enhancement of the equatorward momentum flux and heat flux in EASWJ could lead to the decrease of GPh in SAh. And the enhancement of the poleward momentum flux in TEJ could lead to the decreasing of GPh in Ih while the enhancement of poleward heat flux in TEJ lead to the increasing of GPh in Ih. Furthermore, the heat flux effects from both EASWJ and TEJ area to SAh are more obvious than momentum flux, the linear effects from both EASWJ and TEJ area are more obvious than total.
