Frequency modulation spectroscopy of iodine at 532 nm using a vibrating mirror

[[abstract]]We demonstrate a simple and low cost method to observe the frequency modulation (FM) saturated absorption spectrum of 127I2 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.[[fileno]]2010123030012[[department]]物理
