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