title: Gas-lens effect and cavity design of some frequency-stabilized He-Ne lasers.
abstract: It is shown that there exists an optimal cavity length which should minimize the frequency shifts induced by lenslike effects in intracavity saturated absorption lasers. Ideas are developed which provide a satisfactory explanation for the dispersion in modulation shifts observed in some recent laser intercomparisons.
