Abstract
We describe a simple modification to a grating-stabilized diode laser intended for use in neutral atom cooling and trapping. Modulation of the laser diode’s driving current at microwave frequencies induces sidebands in the laser’s spectrum that eliminate the need for a second laser in a trapping apparatus, yielding a considerable savings in effort and cost. A detailed description of the process for selection and assembly of microwave components is given. In an appendix we list the hardware used, with vendor and pricing information.
