7. Test the shutter functionality by enabling the laser drive electronics. Set the
current to 0A and fire the laser. Observe the shutter while pressing the shutter
button on the laser drive electronics and confirm the shutter is functioning.
8. Increase the operating current to just above threshold. Confirm the shutter is
blocking the laser beam by verifying there is no laser radiation when the laser
is running.
NOTE:
Only replace one steering mirror at a time.
1. Turn laser on, just above threshold.
2. Place an aperture just outside of the output window. Mark a reference point at
least 1 meter from the output window of the laser. This point will be used to
target the laser after steering mirror replacement.
3. Turn off laser.
4. Remove the #8-32 screw and locking hardware holding the steering mirror
assembly to the post. Care should be taken to clean any debris from the inside
of the laser housing that may be generated from breaking the epoxy bonds.
5. Place the steering mirror assembly on a flat surface. To replace the optic, heat
the epoxy with a heat gun. Using a sharp blade, gently pry or cut the epoxy
away from the optic and mount. Care should be taken to avoid injury.
6. Remove any residual epoxy from the mount.
