Abstract
Two-photon spectroscopy has a unique property in cold and trapped atoms: the ability for atoms to absorb either copropagating or counterpropagating photons and still remain Doppler free, but with different recoil distributions. This allow information to be gathered involving recoil and velocity distributions of the trapped atoms. An extended cavity diode laser (ECDL) that operates at 674.1 nm was used to inject a master-oscillator power-amplifier (MOPA) diode laser with a tampered gain region. This diode laser combination (ECDL-MOPA) results in optically narrow, tunable single-frequency radiation. This type of laser setup allows two photon spectroscopy to be observed without the need to build up the cavity.
