| Zusammenfassung | The conditions which must be fulfilled to achieve an absolute diode laset frequency stability of approx. ± 1 * 10 -8 are determined. The use of a reference measurement of the beam power, together with the third derivative of the absorption line as control signal gives the best results. The beam intensity transmitted through the absorption cell must be smaller than 60 μW/cm² The influence of the cell temperature on the spectral position of the absorption line is negligible. The new developed Rb-stabilized diode lasers show a long time stability of ≈ ± 1.0 * 10-8. They can be traced back to the SI unit with this uncertainty. This is sufficient even for the most precise interferometric measurements and makes it possible to use one of the most important advantages of a diode laser, the high optical power, for example for multi channel measurement systems. |
