用激光干涉仪测量等离子体的折射率。激光器的输出穿过等离子体，并被球面镜反射回自身。激光输出的幅度取决于从反射镜系统反馈到激光腔中的信号的相位，反射镜系统形成高Q腔，其谐振频率取决于等离子体的折射率。如果等离子体密度随时间变化，则在腔中激发激光频率下的一系列共振。
A laser interferometer was used to determine the refractive index of plasma. The output from the laser was sent through the plasma and reflected back onto itself by a spherical mirror. The amplitude of the laser output deperids upon the phase of the signal fed back into the laser cavity from the mirror system which forms a high-Q cavity whose resoriant frequencies depend upon the refrac tive index of the plasma. If the plasma density changes with time, a sequence of resonances at the laser frequency is excited in the cavity.
