Hello,
I've been looking for a while but I cant find much information about this topic.
Lets say I have a ND:YAG Multimode laser of 532 nm and its Q-switch (if anyone can explain what Q switch means that will be awesome) and it produces 25mj per pulse at 1 kHz and peak pulse power of 385 kW.
I want to ionize Air or Nitrogen using this laser (I'm trying to make a laser triggered spark gap, basically 2 electrodes one at HV and the other is Ground, the problem is self break down, thats why I'm trying to trigger it using a laser, so the break down voltage doesn't change from every time I run the experiment).
Here is what I understand, Laser will give energy to the molecules of gas, and if this energy is sufficient this molecule will get ionized.. and if I have enough energy to ionize a certain number of molecules I will be able to trigger the electrodes at the voltage I want.
Would the laser I have work? if yes how can I tell if a laser will work? Also if you can explain to me the process because I think I dont understand it correctly that will be great.
(extra info:the distance between the 2 electrodes is around 1 cm, and the radius of the spherical electrodes is 1 cm)
I need your help.
