A complex resonator He-Ne laser at 633 nm was constructed as a local oscillator for measuring the absolute wavelength of a Co_2 laser. It is stabilized by a dual servo-control system. One is a frequency offset-lock system, by which the frequency of the laser is stabiized so as to hold an offset frequency from an iodine stabilized He-Ne laser as a master laser. The other is a subresonator control system, by which the output power of the laser is stablized. The laser oscillates at a single frequency with a maximum output power of 10mW. The oscillation frequency can be turned over a 1.5 GHz spectral range and locked without modulation to any frequency over a range of ±15 MHz of the offset frequency from the master laser. A frequency stability of ±1×10^<-11> and an output power stability of ±4×10<-4> are obtained.
