Is it practical to build a TEA Nitrogen Laser with at least a 10 Joule pulse? Answered

I am building an Electrolaser and I have decided on using a TEA Nitrogen Laser, but I am not sure what the specifications of a laser powerful enough for it would be.

Yes it is.
N2 lasers are extremely easy to build once you have a high voltage supply.

How powerful would the capacitors need to be?

Well they're obviously going to have to be big enough to store >> 10J of energy !
If you know the efficiency of the laser, you can get a number to work with.

Thank you both for your feedback. Does anybody know the efficiency of a TEA Nitrogen Laser?

!!! 10 Joules per pulse is exhagerated for such a laser !!! ...tipycally it manages 100uJ (micro joules = 10^(-6) joules) The nitrogen laser is of nature impulsive so the peak power could be in the order of hundreds of watts (>100kW) but the energy carried by each impulse is very very low. Pulse duration is tipycally 10nsec or less depending on the N2 pressure (the higher the pressure the lower the pulse width and the higher the instantaneous power per pulse)

Looks like the end-to-end efficiency is pretty poor, like 0.1% !!!!!

The wikipedia article looks fairly authoritive to me.
