Electronic improvement of interferometric measurement of dye laser wavelengths

The wavelength of a dye laser beam has been determined with a Michelson interferometer with one moving mirror. The addition and design of a phase locked loop (PLL) to multiply the fringe frequency is discussed. Experimentally it appeared that the addition of a PLL has two main advantages: an improve...

Description
Summary:The wavelength of a dye laser beam has been determined with a Michelson interferometer with one moving mirror. The addition and design of a phase locked loop (PLL) to multiply the fringe frequency is discussed. Experimentally it appeared that the addition of a PLL has two main advantages: an improvement in the resolution of the system by a factor of ten, and an improvement in reproducibility due to the flywheel effect of the PLL.
