Abstract

The output from two grating-stabilized external-cavity diode lasers were injected into a single-mode diode laser. Operating at a wavelength of 780nm, this laser produced 50mW of power with two main frequency components of the same spectral characteristics of the seed lasers. The power ratio of the amplified components was freely adjustable due to gain saturation, and amplification was observed for frequency differences of the two seed lasers in the range from 73MHz to 6.6GHz. This system was used to realize a dual isotope magneto-optic trap (MOT) for rubidium (Rb85 and Rb87). The resulting position and cloud size of the dual isotope MOT was the same as that of the single species MOTs to within ±10 and ±20μm, respectively. We also characterized the additional spectral components produced by four wave mixing (FWM) in the diode laser amplifier and utilized a particular FWM sideband to realize hyperfine pumping and subsequent laser trapping of Rb85 in the absence of a “repump” laser dedicated to hyperfine pumping.
