I know that kind of things could be done by thyratrons, but wikipedia says that they are being phased out by semiconductor devices.
Could anyone suggest which kind of devices can switch on that fast and pass that much current? I've checked thyristors - and all I can get seems to be 1us switch-on time...
I don't need to have 1000A for more than 0.1-1 \$\mu\$S, so I have reasonable thermal budget.
That's for not-so-simple TEA laser.
