I am working on revamping my laser power supply.  I have to
significantly over-voltage my step-up transformer to provide the
voltage required by my voltage quadrupler circuit.
I also get massive ripple on the output, making the laser useless
for light shows.  I think if I can reduce the voltage comming out of
my set-up transformer, I can get rid of the pre-step-up transformers
feeding it, and increase the amount of current going into the circuit
so hopefully the nasty ripple on the output will decrease.

So here are two questions:
1)  I have seen plenty of plans for a voltage quadrupler.  How can I
    make a voltage quintupler or sextupler?  Is there some "formula"
    which can be iterated to make a times-N voltage circuit? 

2)  How can I reduce ripple and/or assure more avaliable current
    from above circuit?
