Modulating the Laser Beam
Following we will outline the steps for converting the optical signals modulated on the
Industrial Fiber Optic laser to electrical signals. Because we do not know what receiver
you will be using to convert the optical signal on the laser beam, please refer to that
receiver's instruction manual as directed in the procedure below.
Your laser and receiver should now be functioning as a free-space optical
communications link. If you are using a VCR as the electrical modulation source,
the video input jack on the laser and a video laser receiver connected to a
television you should now be seeing a picture on the television connected to
video receiver.

Check to ensure that the signal inputs you plan to use do not exceed the
specifications in the Operational Information section of this manual.
Turn off all power to the source which will provide the modulation input to the
laser.
Push the laser's beam stop to its closed position, and make sure the ON/OFF
switch is OFF. (The button should be extended and the pilot light no longer
illuminated.)
Insert the digital or video plug into the appropriate jack on the rear of the laser.
(The ground with these types of jacks established because it is a two conductor
cable.)
Point the laser toward a wall or other non-reflecting dull surface.
Set up your laser receiver, referring to its manual for operating procedures.
Press the ON/OFF switch (SW) on the control panel of the laser. The laser now
should be on, as indicated by the pilot light.
Turn on the power to the signal source.
The amplitude of the exiting laser light should now be modulating according to the
input signals. (You may not visibly see any brightness change in the laser beam.)
Rotate the laser beam stop's handle upward, to its open position.
Target the laser beam on the light detector found on the laser receiver.
Position the receiver or laser as needed, so the laser light beam strikes the center of
the receiver detector.
Adjust the gain on the laser receiver as required to receive signals.
