Abstract:
It is shown theoretically and experimentally that a Fizeau wedge wavemeter typically used to measure laser wavelength can also be used to measure the linewidth of a pulsed or cw laser. Linewidths as small as a few hundred megahertz can be measured by choosing the thickness of the wedge properly.
