Capacitor substitution for TEA nitrogen laser

  1. Oct 7, 2008 #1
    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 [Broken]

    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?
