Abstract
We have used spectrally broadened counterpropagating radiation from tunable diode lasers to cool an atomic beam of cesium. This produces a continuous beam of cold atoms. The injection current to the single-mode diode laser is modulated at 10 MHz, resulting in spectrally broadened light for atomic cooling and optical pumping. The atomic beam is probed with a weak single-mode laser. This is a simple and relatively inexpensive method for producing a continuous supply of cold atoms.
