The oscillation line from a two-mode stabilized inner-mirror-type 633-nm He-Ne laser was locked to the iodine saturated absorption line. FM spectroscopy was used to detect the saturated absorption signal. An iodine cell was placed within the ring cavity to multiply the excited light. When the oscill
