Re: Flash Pump Options

Hi again,

I took a chance and purchased a laser head on . The item text read:
"..., Model: -TM4, Laser head. It comes with the Flash lamp and a
Holmium rod already installed, which are in good condition. The Pump
Chamber holds a 4 by 89 Laser Rod. When installed on the laser head,
the pump chamber was capable of producing 15 Watts of power, when
pulsed at 5 or 2.2 Joules of energy. To produce that Power/Energy, the
Flashlamp was pulsed using a 1.5 Kilovolt, High Voltage Power Supply
with a pulse width of 200:s". I don't really have any delusions of
running this anywhere near the described output but would like to get
something 'noteworthy' out of it. I tried to locate tech. specs. but
haven't turned anything up so far and am trying to find a 'modest'
method to pump it without turning up a 1.5 power supply. Does anyone
have any idea if the installed tube can be driven with anything less
that the described power supply or should I carefully remove it and
look for an alternative? In the past and for different projects I have
taken multiple disposable cameras and used the trigger from one camera
to trigger 4 flashes as the same time, or what appeared to be at the
same time. Is there any value in heading back down that road with this
rod?

You should be able to determine the approximate range of operation of the
lamp based on its dimensions. It's best to use that lamp since the
reflector will be optimal for it, rather than cobbling together a bunch
of little disposable flashes!

See the Laser FAQ, starting with chapter on solid state lasers, for more
info and links.
