Our analytical results indicate that a narrower EIT width of 36kHz and a maximum transmission of 92% can be achieved with a probe beam diameter of 1.5cm. Furthermore, we have also observed a large group delay of 0.3 μs, corresponding to an achievable group velocity of (c/504) m/s<!--[if gte msEquation 12]> style='mso-bidi-font-style:normal'>c style='mso-bidi-font-style:normal'>504 style='mso-bidi-font-style:normal'>m/s.
Based on our findings, we conclude that to achieve a lower EIT width, higher transmission, and large group delay at room temperature, a larger probe beam diameter is beneficial. These results have implications for the manipulation of light in atomic systems and the development of new technologies based on the principles of EIT.
