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.

Sheng
