I have just had a laser tube replaced in a Coherent 90-5. Work was done by
Richard Ballard of Grapevine Lasers (phone 817-488-3137). Work is excellent
and the least expensive as determined by our Univ. purchasing by a bid
process. A Coherent tube was used. I recommend Grapevine Laser to anyone
who needs post warranty laser work.
