With the deepening of the research of vortex light , higher requirements are put forward for thetransmission control of vortex light in various media.The on-off control of vortex optical transmissioncompleted in the three-level heat source subsystem by using the optical pump effect. The transmissior transmittance of signal light is regulated by controlling the degree of detuning of signal light ,the optical poweof pump light and the temperature of rubidium atom gas pool, so as to realize the on-off control of vortex opticatransmission.lt combines theory with experiment , so that students can fully understand theoretical knowledgthrough experiment , and cultivate and improve students' practical ability and innovation conseiousness
