15. Replace HR assembly. Remove pinhole from location 1. Verify HeNe
reflection from HR mirror is aligned back to HeNe output.
16. Replace pinhole in location 1.
17. Replace shutter.
1. Replacement of the laser module should only be performed if the module
fails. Replacing a laser module will change the performance characteristics of
the laser from the original ATP Test Report Data Summary provided with the
laser.
ESD CAUTION
The laser diodes in the Laser Diode Module are sensitive to Electro-
Static Discharge (ESD). Never handle the module without being properly grounded
through the use of properly installed and maintained grounding wrist straps or other
ESD control devices. Subjecting the module to static shock can seriously damage or
destroy the diode bars, and will void the product warranty.
2. If applicable, carefully cut the clear insulation around the electrical lugs on the
laser module and disconnect the wires.
3. Identify the plumbing jumper ends that correlate with the positive and
negative markings on the diode module cover. Use 11/16 in or 18 mm stub
wrench to remove the plumbing jumpers.
4. Remove the three (3) 8-32 x 5/8" screws bolting the module onto the optical
bench of the laser. Carefully lift the diode module out of the laser.
5. Remove the rod dust caps from the new pump module and inspect rod ends.
Ensure that the sealing nuts on the module elbows are screwed all the way out.
