Abstract:
The present invention is directed to a modulated which includes a semiconductor laser being driven by direct current for frequency tuning, and an AC current with two radio frequencies that can generate repump and Raman frequencies, such that only one laser is needed to produce all the frequencies required to operate an atom interferometer. The present invention is also directed to a method of double modulating a laser to produce all required frequencies for an atom interferometer.
