Hi,
Does anyone have experience trouble-shooting the Coherent Enterprise laser,
or know of a service company in the UK who do? Coherent UK tell me that
they don't touch them, and the OEM doesn't offer contract cover (which came
to light after we bought it), so I'd like to have a go at fixing it before
we hand it over to be shipped back to the States.
My problem is that the power supply continuously produces a high pitched
loud whine but won't lase. I presume the whine is related to it generating
the striking voltage to generate the plasma, since it normally produces this
whine for two or three seconds immediately before lasing. No fault lights
come on (except the current limit light, which stays illuminated as it
normally would until lasing commences), and the laser emission warning
lights work, there's no tube current.
Any ideas would be appreciated,
cheers
Ray
ps I had a similar problem with another Enterprise, the OEM in that case
swapped the system and I never found out what the cause or cure might be
