摘要
介绍了用激光干涉法测量等离子体电子密度的原理。研究了ＨＣＮ激光器及其输出模式和传输特性，并给出七道远红外ＨＣＮ激光干涉仪的改进及其最新结果。在光路改进中解决了原光路的一些重要问题。
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.
