moves to the 200 mm position in case it is not there yet. This can take a few seconds. The
initialization can be forced manually by clicking the "Refresh Stage List" button in the
Device
Selection window . After the stage is identified and its serial number is read from its
EEPROM, double click the DDS100(/M) button in the device selection window.
7.2.7 M² Measurement
Prior to starting the Beam Quality measurements with the M2MS and a BP209 Series Beam
Profiler, the beam of the laser under test needs to be aligned to the M2MS Measurement Sys-
tem. It is important that the beam center hits the center of the Beam Profiler's aperture at every
position of the translation stage. Please read the following section carefully and follow the in-
structions.
Please open the M2 measurement panel via the icon to arrive at the alignment and mea-
surement GUI.
To prepare for and perform a M2 measurement, please click the M
2
icon on the left side of the
window. The top panel shows the Alignment tab, the M
2
measurement tab, and the
Live Adjustment tab. Please start with the Alignment of your system.
