 This characterisation is at many points compared to a {{ :groups:mg:project_ptb-cavity:105638_test_report_rev4.1_20mw_automated.pdf |report}} by rio on the factory test of the diode. The graphs taken from the factory test report use thick blue lines, the others use fine black dots. This characterisation is at many points compared to a {{ :groups:mg:project_ptb-cavity:105638_test_report_rev4.1_20mw_automated.pdf |report}} by rio on the factory test of the diode.

 +To describe the instability of the measured values, the Allan deviation/overlapping Allan Deviation is used. There is a [[https://en.wikipedia.org/wiki/Allan_variance|Wikipedia article]] which explains the Allan deviation very well.
