Abstract

Diode lasers in particular are useful in atomic physics because they are durable, compact, and relatively inexpensive. Unfortunately diode lasers also have linewidths that are much wider than atomic transitions. One common method to narrow the linewidth of diode lasers is to add a reflection grating outside the laser, creating an extended cavity diode laser (ECDL). While ECDLs are effective at narrowing the linewidth, they also introduce so many variables that affect the wavelength of the laser that small changes in the laser’s environment can cause the laser to mode hop, or jump to an entirely different wavelength.
