An active frequency stabilization system for the high power argon laser has been developed. This system utilizes a double frequency reference consisting of both an optical cavity discriminator and a molecular resonance discriminator. Unlike most stabilization systems employing a molecular resonance standard, the technique presented here does not require any modulation of the laser frequency. A frequency stability of one part in 10 to the 8th (±3 MHz) over periods of several minutes has been achieved.
