We preset detailed stability measurements on six He--Ne lasers which have been stabilized by matching the intensity of the two orthogonal polarization modes. The frequencies of five different lasers were closely monitored for 1 month. Another laser was studied for 2 yr. All the lasers exhibited a stability of 1 part in 10/sup 10/ over the periods of about an hour and better than 1 part in 10/sup 8/ over 1 yr. An absolute accuracy of atma1 part in 10/sup 9/ can be attained by interpolating the linear drift between calibrations performed 6 months to 1 yr apart. These 1-mW lasers are rugged and simple to operate.
