 Dopplerfree Saturation Spectroscopy on D1 line of Potassium:
   * 1st the two beams with similar intensity are generated by the beam sampler and are send trough the glas cell
-  * one part of the initial beam is going trough the sampler to a double pass aom and then in the other direction trough the glas cell, crossing inly one beam
+  * one part of the initial beam is going trough the sampler to a double pass aom and then in the other direction trough the glas cell, crossing only one beam. Important: the beam coming from the aom must have a much higher intensity!
-  * the first two beams, coming from the sampler trough the ell are than monitored by the PD. The signal is substracted
+  * the first two beams, coming from the sampler trough the cell are than monitored by the PD. The signal is substracted
+  * in or case e use the aom to create the peak on one side of the mainpeak. This is important for the lock-in scheme
