TLDR
In this paper, an optical heterodyne polarization interferometer is described for the precision measurement of the change in the state of polarization of a light wave induced by polarizing optical devices.Abstract:
We describe an optical heterodyne polarization interferometer that can be efficiently used for the precision measurement of the change in the state of polarization of a light wave induced by polarizing optical devices. This technique is used to measure the change with wavelength of the phase retardation of a quarter-wave plate. A theor- etical derivation is presented to permit computation of the wavelength dependence of the phase shift induced by a quarter-wave plate.read more

TL;DR: In this paper, a series of experiments of type II mixing of previously chirped 50 fs pulses were conducted and it was found that if the input pulses have chirps of opposite sign, the bandwidth of the generated pulse can be broader than that with transform limited input pulses under some conditions and significantly narrower under others.
