I recently obtained a 5mW HeNe laser tube at a local hamfest. Unfortunately the vendor did not have any power supplies. My project, then, is to design a solid state HV supply for this thing. Here's the rub - I've never designed a voltage multiplier circuit before. If anyone could lend me a hand, I'd really appreciate it. Here are the specs as I see them: 12-14V dc input 5KV out, open circuit 1.8-2KV out at 6.5 +- 0.1 mA I'd rather not use a transformer, but then I' have to have ~9 doublers. If a transformer is a must, how do you choose the slope of the current load line? Any help would be greatly appreciated. -- David E. Tiller davet@tsdiag.ccur.com | Concurrent Computer Corp.

The March 1989 issue of Radio Electronics has an article on building a
"universal" laser power supply. Check your local library or a friend's
subscription.
