A high time resolution polarimeter for laser analysis.
A technique that has a time resolution capability of better than 0.1 microsec has been developed for the measurement of the polarization of a light beam. This technique has proven useful in measuring the polarization of pulsed laser beams because changes in polarization from spike to spike also may be measured. In essence, the method of measurement is to split the beam into identical components and to pass these components through various polarization analyzers at different angles. The intensity of the beams after passing through the analyzers is measured by photomultipliers, and the output of the photomultipliers are recorded on oscilloscopes.
