Dear Listers,

I am looking for an inexpensive deep UV (~ 280 nm) LED or pulsed laser
light source for microscopy imaging.  I want to have the maximum output
power at least in the mW average.  The pulsed laser should at least a 10MHz
repetition rate.  Any suggestion would be appreciated.  Thanks a lot in
advance.

How 'inexpensive' are we talking here?  Thousands or tens of thousands?  If
you are in the Thousands then you are looking at a pulsed LED.  If you can
afford much more then you might be able to get some kind of laser.  If you
already have access to some kind of pulsed laser at your facility with
sufficient energy then you might be able to frequency triple it to get the
wavelength range you need at a relatively low additional cost.

Hi Craig,

I would like to be in the "Thousands" range.  Thus, I will not go for THG
(or FHG) of a 840 nm (or 1064 nm) ps or fs pulsed laser.  I am also aware
of a few options for the pulsed LED in the 280 nm range.  But their maximum
output power is only a few uW.  I am OK with a CW LED if the power is in
the mW range. Thanks.

I'd try this pulsed generic source from Thorlabs.  It's a modulated driver
optimized for running LEDs.  Their stock options only go to 365nm, but if
you can find a compatible 280nm LED it should work for you.  Thor might be
able to help you out if you email them.
