Laser stability must be defined in terms of the appropriate observation period, usually a second, an hour or a day, and the expected changes in the environment during that period. The relative importance of sources of instability of power output has been investigated and related to various designs of the HCN laser. The design of the NPL-GEC laser has been based on this investigation.
