WebJan 11, 2024 · Yes it is possible. You need a strong laser though, with peak powers in the terawatt range. The key thing for that to actually work over distances longer than a few mm or cm is an effect called filamentation. This is a kind of self-guiding property of air at very high light intensities (starting at TW). WebStep 9: The HV Pin Grid. Once the cap/diode array is glued in place, then the HV pins can be placed and mounted. I used pieces of the ega tube trunking hot glued and drilled for a small cable tie. Then the fan/grid assembly is spaced (1cm) from the pin tips, and the trunking is sawed off to size. is free flex card a scam
