Prisms (fs Configuration)
CAUTION
DO NOT remove or adjust the prisms to clean them: they are aligned
at the factory and are not to be disturbed unless specifically told to do
so elsewhere in this manual. A service call might be required if disturbed.
Clean them in place.
1. Close the pump laser shutter.
2. Clean the prisms in place. Use a separate folded tissue and a hemostat
to clean the surface of each prism as outlined in step 3 of "General
Procedure for Cleaning."
3. Open the pump laser shutter.
Tisapphire Rod
Laser performance is extremely sensitive to dirt on the rod surfaces. A
small portion of rod protrudes from the end of the holder to allow easy access
for cleaning. Refer to Figure 6-5.
WARNING
NEVER remove the rod from its mount. The rotational alignment of
the Ti:sapphire rod is critical and has been optimized at the factory.
Any modification or adjustment other than that made by a qualified
Spectra-Physics Lasers service engineer will void the warranty.
1. Close the pump laser shutter.
Birefringent Filter (ps configuration)
2. Clean the rod surface using a folded tissue in a hemostat according to
step 3 of "General Procedure for Cleaning Optics."
3. Open the pump laser shutter.
Typically, only the upward-facing surface of the birefringent filter gets
dusty, and it can be cleaned without removing the filter.
1. Close the pump laser shutter.
2. Clean the top surface using a tissue and hemostat according to step 3
of "General Procedure for Cleaning Optics."
WARNING
The birefringent filter stack is carefully aligned at the factory to orient
the filter plates at Brewster's angle. NEVER disassemble the filter
stack, nor remove the main birefringent filter mounting assembly from
the laser.
