Abstract

We present recent results on compact GaN based laser sources, primarily designed for cooling and trapping atoms and ions. We show various designs used for miniaturised, direct-generation laser sources in the UV-green part of the spectrum targeting multiple atomic species. We show results from a line narrowed 369nm ECDL for Yb+ cooling, a 397nm frequency stabilised source for Ca+ cooling and a 422nm butterfly packaged ECDL for Sr+ cooling.
