Abstract :
We demonstrate a simple and low cost method to observe the frequency modulation (FM) saturated absorption spectrum of /sup 127/I/sub 2/ at 532 nm. We use a vibrating mirror with modulation frequency of 570 kHz to modulate the laser frequency. Preliminary result is shown for the iodine P(54) 32-0 line.
