摘要：

In this manuscript, we observed narrowing of electromagnetically induced transparency (EIT) spectral width by using superimposed Laguerre-Gaussian (LG) beams for coupling light. EIT with narrow transparency width has a potential application towards slow light for quantum memory devices. LG beams of sigma(+) and sigma(-) polarization are superimposed and used as coupling light for an EIT experiment. A theoretical model is discussed using a semi-classical treatment and the experimental part confirms the narrowing of EIT width for higher values of 'l'.
