Modelling of frequency stabilization of diode laser based on 3rd, 5th and 7th harmonic method

The stabilization of diode lasers with a wider spectral line based on the iodine absorption cell, has been examined with a stabilization method of a 3^rd, 5^th and 7^th harmonic deviation. Possible stability levels, according to the width of diode laser´s spectral line have been checked. The 3^rd, 5^th and 7^th harmonic deviation stability method have been compared.
