Abstract
The set up of a stable and monochromatic CO2 laser has necessitated many systematic studies which are described.The observation of beating between modes led us to define the conditions of oscillation of a single mode. The use of a grating in the cavity gave a laser power on a single line. The construction of a single line, single mode laser gave us the possibility of ascertaining the constancy of the length of the cavity and of obtaining a power stability better than 1.5 × 10−2 during 1 h.Keywords
