Aligning the Turning Mirror, Apogee Elite Nd:YAG
The Apogee Elite Nd:YAG resonator uses a tuning mirror and beam combiner to align the Nd:
YAG beam to the fiber assembly. Before aligning the mirror, inspect the turning mirror and
beam combiner for damage. For aligning and measuring resonator energy, please refer to the
Final Test and Calibration Procedure.
IMPORTANT: Aligning the turning mirror is a critical function.
Inspecting the Beam Combiner Glass/Removing the Holder
1. Disconnect fiber # 96 from the beam combiner assembly.
NOTE: For the Apogee 5500/Acclaim 7000 lasers, also disconnect P14 (LED).
2. Loosen the two 8-32 socket head and remove the beam combiner.
3. Loosen the two 4-40 setscrews that secure the pick off holder on the beam combiner
assembly. Remove the holder.
4. Inspect the beam combiner glass for any damage, and replace the glass if necessary.
Make sure that the new glass is installed in the same orientation.
Replacing the Beam Combiner Glass
CAUTION: Verify calibration of the energy monitor when replacing the beam combiner
glass. Recalibrate if necessary, or the laser may operate incorrectly.
Replacing the Glass Only, Apogee Elite
1. Remove the holder as described in the section above.
2. Remove and replace the glass assembly by removing the three holding screws and the
wavy washer.
3. Install a new combiner glass and verify alignment of the Nd: YAG laser beam and aiming
LED, and then realign if necessary.
4. Reinstall fiber #96 and verify the energy. If necessary, recalibrate as described in the
Final Test and Calibration Procedure.
NOTE: The beam combiner is coated on one side only. This coated surface must face the
laser rod. A black dot on the glass indicates the uncoated surface. Remove this dot using
methanol and a lens tissue or cotton swab before gluing the new glass in place.
