Beam Combiner Inspection/Replacement Procedure
The beam combiner is coated on both sides to maximize the optical paths of both the PDL and
YAG lasers. The first surface (from the perspective of the PDL head) is AR coated for the dye
wavelengths and the second surface is coated to maximize the transmission of the dye and to
reflect most of the YAG. There is some reflection and leakage, respectively, so care should be
exercised when servicing to not look into the beam path at this point. The resonator-interconnect
PCB support serves as a beam stop.
1.
Inspect the surface of the beam combiner with a flashlight. Any discoloration aside from
a pristine, uniform surface may represent damage. It may be necessary to remove the
resonator interconnect PCB and its sheet metal mount to gain viewing access to the optic.
2. Remove the entire fiber block to gain access to the hold down screws (3x). Remove the
optic and frame.
3. Attempt to clean the surface with lens tissue and methanol. If it cannot be cleaned,
replace the optic.
4. When replacing the optic, tighten the screws firmly until the frame seats against the
Ultem block.
Fiber Alignment Procedure, PDL
In a properly assembled laser, there is no adjustment necessary. Both the beam combiner and the
focus lens are not adjustable, however, it may be necessary to confirm that the focus spot is on
the center of the alignment pin in order to rule out a mechanical issue, such as a loose or cocked
focus lens. Follow the Fiber Alignment Procedure, YAG, but operate the PDL laser slightly
above threshold.
Turning Mirror Inspection/Replacement Procedure
The turning mirror is a vital part of the beam train—it represents the only optic that is adjustable
in the beam train. Because of this, the replacement of this optic should be done very carefully.
1.
Move the aim beam collimator out of the way. First remove the 4-40 screw that clamps
the collimator assembly to the resonator port, and then move the assembly out of the way.
2. Inspect the surface of the turning mirror with a flashlight. Any discoloration aside from a
pristine, uniform surface may represent damage.
3. Remove the three 4-40 adjustment screws and the compression springs. It may be easier
to remove the entire fiber block to gain better access to the screws.
4. Attempt to clean the surface with lens tissue and methanol. If it cannot be cleaned,
replace the optic.
5. When replacing the optic, compress the springs fully until the frame seats against the
Ultem block, and then back them off each approximately one turn. This positions the
optic correctly, maximizes the resistance of the threads to eliminate the screws backing
out, and allows enough adjustment range.
