If the laser has its own power supply: Connect laser power supply to the laser (laser
should glow now).
In the case of a system, including Motorized Mirror Mounts (MMMs):
o “M1” connector at rear “M1”cable MMM “M1” (first actuator mirror in the beam
path)
o “M2” connector at rear “M2”cable MMM “M2” (first actuator mirror in the beam
path)
In the case of a system including piezo actuators
o "piezo actuators" connector at the rear Y-cable (25pol SubD male "piezo actuators"
2x HD15 female “A1”, “A2”) to Piezo Actuator “A1”, and Piezo Actuator “A2” (Or Y-
shaped adapter SubD 25 2x HD15)
Installation and start of the visualization software "Kangoo"
o Install "Kangoo", following the instruction s of the "Install.exe" program of the installa-
tion CD (In case of problems see related chapter on "Kangoo Installation")
Setting and testing communication parameters between µC and PC
o Start „Kangoo.exe“. If communication window (terminal window) is off, switch it on:
“Communication / display com window”
o Switch on Aligna System. Communication, displayed in different colours should be
seen at the COM window
black: commands and requests of PC
green: micro controller (not interpreted),
red: micro controller, interpreted by PC)
blue: manual user inputs
o If this is not the case (only black words=PC requests, but now answers of the µC) the
COM settings are wrong, mostly the COM number:
Right mouse click to COM window, “COM Parameters”, “check!”. Now in the list all
available COM numbers are listed. Select the one of the USB port, click “Open COM”.
Click to COM window; hit the “Return” key. Answer should be “(no command)” (be-
cause you entered an empty line and <RETURN>.
(If this is not successful: see chapter on setting up USB port)
o Select configuration "Aligna Basic Use"
(for more detail see chapter " Setting up the Aligna
®
System by Help of Kangoo ")
Coarse pre-alignment of the opto-mechanical test setup
For the Plug'n Play Kit the mechanical AND parameter pre-alignment is already done!
o The intensity of the (cw) test beam, coupled out to the pointing detector, should be in
the order of 200 µW to 2 mW. (For using pulsed lasers, see below!)
o If irises are present: Pre-align laser beam to irises by means of the manual alignment
screws to define the target beam path. Align the beam for best performance for your
experiment.
(If there is an iris BEFORE the detector beam sampler: Do not forget to open this iris
finally!)
o OR: Pre-align laser beam, so both detectors A and B are hit approximately in the mid.
(You can open the detector covers to watch the spot positions.)
o If no intensity is seen at one or both detectors, alignment of the detector and/or the
beam sampler is necessary (depending on the type of pointing detector you ordered):
