During measurement of the refractivity of a pulsed plasma, we have detected, with the help of a Jaminlike interferometer, the optical path variation caused by lamp windows. We attribute this variation to two causes: mechanical vibration and the slow cooling that follows the sharp heating. We conclude that neither has any influence on the measurement of plasma refractivity.
