Abstract

The principle of interferomter for measuring the electron density of plasma is described. HCN laser, its output modes and the propagation of EH 11 mode in free space are studied. Improvement of 7-channel FIR HCN laser interferometer and its new measured results are presented. We solved some important problems in previous optical system and make the signal increase about one order.

Keywords
