OPERATING THE LASER
1. Safety first. Mount the laser properly so that the laser
beam will not point to any person’s eyes. Please check
appropriate local regulations and observe them properly.
2. Insert the control switch key into the keyhole and keep it
in the OFF position.
3. Check the AC main voltage by someway and make sure
that it is within the voltage required by the power supply.
If yes, plug the power supply input terminals into the AC
main and insert the output plug into the socket for the
power supply on the back of the laser, see Figure 4.
4. Insert the interlock switch cable plug into the interlock
switch socket, see Figure 4. This cable can be connected
to a mechanical switch if the laser needs to be controlled
remotely, to an electronic switch if the laser needs to be
controlled by an electronic circuit, the digital I/O port of
a computer if the laser needs to be controlled by
software, or simply short circuit the cable if choosing not
to control the laser by this switch.
5. Turn the control switch to the AL (stands for Alignment)
position for aligning optical components with this laser.
At this position, the laser will emit weak laser beam,
which will not be too bright for naked eyes to do the
alignment work.
6. To turn on the laser:
A. Rotate the control key switch to the ON position,
which turns on the TEC (ThermoElectric Cooler)

control circuits, and wait for a few seconds till the
TEC LED comes on. Now, the laser is brought
into the right temperature for working.
B. Turn the control key switch to the LD position and
the laser is now turn on to its full power.
C. Wait from a few seconds to 1 minute, the laser will
emit single mode beam with long coherent length.
7. To turn off the laser: rotate the control key switch to the
OFF position.
8. The CL (stands for calibration) position for the control
key switch is for calibration usage, this function is not
needed for ATMF102 laser modules, therefore, the AL
position is not utilized.
9. These are the “Do not Do’s”:
A. Do not turn on and/or off the laser by inserting the
power supply plug into the socket.
B. Do not turn on and/or off the laser by the input AC
voltage to the power supply.
C. Do not turn on the laser before the TEC LED is
not lit.
D. Do not place the first optical component too close
to the laser and try to minimize any back
reflections, otherwise, the laser beam may lose its
important and valuable features: single mode,
mode-hop-free, and/or having long coherent
length.
