Abstract

In this paper, a preliminary result for an iodine frequency stabilized tunable diode lasers at 633 nm is reported. The frequency stability of the diode laser was 2 X 10^-11, the tune ability was 10 nm and the line-width was 100 kHz. In addition, five groups of stronger hyperfine transitions of iodine molecule, which are available to be reference lines for diode laser frequency standard, beside the well-known transition R(127)11-5 at 633 nm region were observed by means of saturated absorption in the configuration of external iodine cell and their absolute frequencies were measured by a spectrum analyzer and a scanning Fabry-Perot cavity. The program for calculating the hyperfine structures and strength of transitions for rotational vibrational bands of iodine molecule was developed and the predictions for possible transitions around 633 nm including the transition strength are given.
