Two methods are described for stabilizing the output of an HCN laser: an automatic power control system suitable for use in a variable temperature environment, and an automatic frequency control system requiring stable laboratory conditions. The former can stabilize the laser output power to within +or-2% of a predetermined level for approximately 200 h. Some of the principles of operation are applicable to other devices.
