4.2 Troubleshooting

MLC8xxx / page 68

Is the laser diode poled correctly?

If not, change the polarity of the laser diode corresponding to the type of

MLC-module used (AG or CG)

Is the photo diode connected properly?

Check the connecting cable.

Do you use a temperature window with inappropriate setting or with no TEC

connected?

Change settings, install TEC or turn off the window function

If you don’t find the error source by means of the trouble shooting list or if more
modules work erratic please first connect the

Thorlabs-Hotline

([email protected])

before

sending the whole PRO8000 (-4) / 800 system for

checkup and repair to

Thorlabs
