To be updated. Short version: The PID loop with the Amrel bench PSU and Keithley 199 DMM is successful and will be improved and expanded. On the software side the scripting is done on GNU Octave with use of the instrument control package. All test equipment is connected via GPIB, controlled by the linux GPIB software.

This computer controlled PID loop is also used for controlling the temperature of the laser diode bar of the CW sidepumped YAG laser. This way no special temperature controller is needed and the standard test equipment can be used.
