SYSTEM FOR ANALYZING PLASMA DENSITY

摘要

PURPOSE: A plasma density analysis system is provided to analyze density distribution of plasma of which a refractive index is changed in a medium by using a width shear interference pattern. CONSTITUTION: A light source(100) irradiates a laser beam. A beam amplifier(200) successively amplifies the laser beam. A light path guide reflects the laser beam having plasma density information. A plasma density distribution analyzer(500) obtains interference information of the reflected laser beam and beam intensity information of the transmitted laser beam.
