Electron Density Measurement in the HCN Laser Using Faraday Mode Splitting Technique.


The Faraday mode-splitting, or self-heterodyne, technique has been used to measure electron density along the optical axis of the HCN laser (337 microm). The measurement indicates an afterglow electron density of 4.5 x 10(11) cm(-3); this result agrees with microwave measurements made across the laser axis. The sensitivity of the measurement is about 2… (More)
