Semiclassical limits to the linewidth of an atom laser
Semiclassical limits to the linewidth of an atom laser
We investigate the linewidth of a quasicontinuous atom laser within a semiclassical framework. In the high flux regime, the lasing mode can exhibit a number of undesirable features such as density fluctuations. We show that the output therefore has a complicated structure that can be somewhat simplified using Raman outcoupling …
