|Modelling of frequency stabilization of diode laser based on iodine absorption cell

The possibility of stabilization of diode lasers, lasers with a wider spectral line based on the iodine absorption cell, has been examined with a stabilization method of a 3 harmonic deviation. Possible stability levels, according to the width of diode laser’s spectral line, have been checked. It has also been checked the change of the signal of the 3 harmonic in dependence with the frequency and depth of the modulation of the stabilized diode laser.
