Construction of parallel grids acting as semitransparent flat mirrors in the far infrared.
The construction of metallic wired grids used as semitransparent mirrors is described. The reflectance of such grids varies widely with the polarization direction of the beam. The measured characteristics are compared with those calculated. These grids are used in the cavity of an HCN laser and determine the polarization direction of the output beam.
