Abstract

A new method in the field of holographic interferometry used for plasma diagnostics is presented which allows us to reduce the irradiation onto the interferogram caused by the plasma. The advantages of this new technique are demonstrated in two examples: determination of the electron densities in a high-radiation Xe-lamp applying non-resonant two-wavelength interferometry, and investigation of the degree of population inversion in a He-Ne laser discharge by heterodyne resonant holographic interferometry.
