Pagination or Media Count:
The linewidth and frequency associated with the ground state hyperfine energy fo Rb 87 has been studied. A stable single mode semiconductor laser is used to optically pump Rb, in order to obtain a highly collimated, monochromatic light source. The laser is stabilized by locking its optical frequency to the Rb absorption line center. The dependence of the hyperfine frequency and resonance linewidth have been measured as a function of temperature, light intensity and microwave power and a theoretical description of the linewidth vs. temperature data is presented. Keywords Optical pumping Rubidium Frequency standard Frequency shift Light shift Density matrix Buffer gas Linewidth and Magnetic resonance.
