1.
Loosen the X-axis, Z-axis, and rotation clamp screws
on the AOM unit.
2.
Open the laser shutter, and adjust along the X-and
Z-axes so that the laser beam passes through the
AOM opening. Then, turn off the power for the AOM
controller to pass the 0th-order light.
To adjust in the Z-axis direction, use the adjusting
screw with the clamp screw completely loosened.
The transmission ratio of after-AOM to pre-AOM
should be approximately 95%.
3.
Detach the laser unit front sheet metal cover.
4.
Turn off the AOM controller [REMOTE] switch.
(If the [REMOTE] switch is in the ON position, the
AOM controller will be turned on automatically when
the PC is turned on. If the [REMOTE] switch is in the
OFF position, the AOM controller can be turned on
or off independent of the PC.)
