| Vapor pressure dependence of spectral width of EIT in Lambda-level cesium molecular system (2009) | |||||||||
Abstract | |||||||||
| We have studied electromagnetically induced transparency (EIT) in diatomic cesium molecules in a vapor cell by using tunable diode lasers. We have observed a sub-natural Lambda-resonance in an absorption molecular band at different cesium vapor pressures. The width of the EIT resonance shows a linear dependence on cesium vapor pressure. Narrow Lambda-resonances in molecules can be used as frequency references for femtosecond laser frequency combs.. Comment: 7 pages, 3 figures | |||||||||
