Capacitor substitution for TEA nitrogen laser

[guipenguin]

My next project is to build a simple TEA nitrogen laser, as seen here: http://photonics.tfp.uni-karlsruhe.de/1/a-homemade-uv-laser.html

Would it be acceptable to substitute two strontium titanate ceramic caps, each rated 50KVDC @ 910pf, in place of the suggested aluminum foil / plastic dialectic plate caps?

My hypothesis would be if such materials were available than it would be beneficial for lower losses would be encountered with a commercial capacitor.

Let me know what you think about using a couple HV doorknob caps here.

Thanks,
John

What is the capacitance of the foil/plastic capacitors? Equivalent to your ceramics?
