WebbAn amplitude-modulated semiconductor laser is used to excite a 9.2-GHz Raman transition in a cesium atomic beam. Separated-field Ramsey fringes as narrow as 1 kHz wide are observed with a high signal-to-noise ratio, even for semiconductor laser linewidths as wide as 20 MHz. These narrow resonances have potential application in the development of … WebbFigure 2 shows Ramsey fringes measured without average (one shot per point). The linewidth of central fringe is measured to be 1 Hz with S/N of 600.
