In this study, we report achieving more than − 7.8 dB of intensity-difference squeezing (IDS) in two-mode squeezed states from hot 85 Rb vapor and − 5.0 dB from hot 87 Rb vapor, utilizing a fiber electro-optic modulator (EOM) within a single home-made diode laser system. By mitigating the effects of undesired multimode from the EOM on the squeezing, we experimentally demonstrated the IDS of 85 Rb and 87 Rb atoms within a single experimental setup, benefiting from the EOM's ability to provide higher frequency shifts. This advancement may expand the scope of applications for hot atomic-vapor-based quantum technologies, leveraging the capabilities of the EOM.
