First- and third-derivative signals of saturated absorption in iodine 127 molecular vapor are detected by using a frequency-modulated 190-cm-long 633-nm He-Ne laser with a Fox-Smith--type resonator and an iodine absorption cell which is set outside of the resonator. Aiming to stabilize the laser with unmodulated output, a retroreflector-type optical modulator is added to the above system, and the first-derivative signal is obtained by external modulation. Comparing the obtained signal with those obtained by the frequency-modulated laser, possibilities to detect the third-derivative signal by using the optical modulator and to stabilize the unmodulated laser are found.
