| Abstract: | The electromagnatically induced absorption (EIA) is obtained in degenerated cycled cesium atomic two-level transition of 6S1/2F=4—6P3/2F'=5. The effect of the magnetic field on coherence of the atom is also investigated experimentally. When external magnetic field is applied, the mixed structure of electromagnetically induced absorption and transparency is obtained in the transition of 6S1/2F=4—6P3/2F'=5. The experimental results are in agreement with theoretical analysis of C.Y. Ye et al. (2002). |
