WebA new technique was developed to measure the natural linewidth of an optical transition. It tunes the frequency of a laser precisely across the resonance using an acousto-optic modulator. The transmission of the laser through a cloud of atoms was monitored using a CCD camera. This work studied the 5S1/2→5P3/2 transition or D2 line of 87Rb. The … There are a number of effects which control spectral line shape. A spectral line extends over a range of frequencies, not a single frequency (i.e., it has a nonzero linewidth). In addition, its center may be shifted from its nominal central wavelength. There are several reasons for this broadening and shift. These reasons may be divided into two general categories – broadening due to local conditions and broadening due to extended conditions. Broadening due to local conditions is du…
