I have done this with the 638 line, and it takes some fiddling but it is
possible for mere mortals to do. One key point is to make sure the exit
port of the new laser is at the same location as the old one. If you get an
identical replacement this should not be an issue. There are pointing
optics in the LU that will need to be nudged to get good coupling into the
launch fiber. Be very sure to only touch optics the Argon passes through or
you will throw off the alignment of the other lines. One final caution is
that the Argon passes through an AOM for control. This may need to be
recalibrated to properly modulate the lines but you might be OK if you can
match the original alignment closely enough. As always, practice
appropriate eye safety when working with lasers.
