I built a laser almost 15 years ago using almost exactly the model your
describing here - but without the external coil. For power we used twin
automotive ignition coils in addition to a 5 or 10 stage voltage multiplier,
interrupted with a normal v8 car distributor. The result was a very heavy
continous arc across two heavy metal plates approx. 15 inches long and
inches apart mounted in a rectangular clear plastic 'tube' with two tap ponits
for gas entry and exit. used to provide an interesting UV lase output. Was very
cheap, easy to make and for it's size quite powerful.
Hope this helps.
