Hello,

Our Coherent UV Enterprise argon laser (used for 351nm, 364nm) seems to be
dying.  This is for an Olympus Fluoview 500 system.  Anyone have good/bad
experience with a 375nm (or other UV lower than 405nm) diode laser?  Are
these expensive?

I performed a search of the archives and found a post on exactly this issue
from 2006, but it's probably too long in the past to reply to.

We have a coherent Genesis 355 nm diode laser on a Leica SP5 and we are very happy with it. Cost is similar to 405 diode as far as I am aware.
I have also used the Enterprise on another instrument and results are comparable.

Hi Dan,

You can have your UV Enterprise serviced by Evergreen Lasers (east coast
- may be lower shipping costs) or Laser Innovations. Which is better for
you - call the companies and for price and turnaround time, and check
the archives here for user experiences.

If you have an Enterprise I and any of its components are on the last
leg, whether tube, power supply and/or chiller is dying, L.I. has
replacements.

Hi Dan,

we have a Picoquant LDH-D-C-375 laser on our FV1000. It is a pulsed laser
which can be also used in CW mode. We use it mainly for uncaging or DNA
damaging (both in pulsed mode). We are very happy with this laser. I don´t
exactly know the price, but maybe it is not far from the range of 405 nm
lasers.

There is also a 355 nm CW laser available from Cobolt ("zouk 355"), but I
did not try it.

No commercial interest.

Stefan
