| Abstract: | By means of an external ring optical cavity and FM spectroscopy the saturated absorption signal obtained in the investigation reported here is with the highest SNR (signal to noise ratio)till now in the field of high sensitive spectroscopy at the band of 612 nm,The important factors about high SNR are discussed.The iodine li- nes in the region of 612 nm and the frequency spectrum of FM signal are also shown in this paper.As the results obtained in this investigation using the system set up by the author,the 612 nm laser could be stabilized in the level 10-~(14). |
