“Atom-Light Interactions: Generating New Coherent Light Sources”
The laser has become both a very common and important technology. However, there are still important frequencies where effective lasers are hard to develop. In this talk I will explore one method for developing novel laser sources, called parametric four-wave mixing. By controlling the interaction of existing laser sources with rubidium atoms, it is possible to have coherent light emitted using transitions between atomic levels. The limiting factors to high power output will be discussed, as well as possible solutions. Current experiments have shown the realization of this process at 420 nm, a desirable wavelength for quantum computing.
