Hi Gerry,

The Titanium Sapphire laser is a solid crystal laser charged pumped from say a 5W argon laser.


The titanium laser has no real moving or electronics parts from what I understand. This is interesting in that it could be "floated" above ground potential. Thus you could have the laser "switch" floating at say 500kV AC and turn it on from say 100 feet away by hitting it with the Argon laser. Almost a perfect super-HV super high-current totally isolated switch!!

I think the price of the Ti lasers are pretty reasonable too and they should have a very long life.

I can just see it now. The lightning follows the ionized filament all the way to the laser. No more laser :o))Gerry

They employed their Teramobile laser, whose pulse lasts for a mere 100
femtoseconds and packs a peak power of 5 terawatts

That's 100E-15 seconds * 5E12 Watts = 0.5 Joules... if I got my prefixes

WOW!! The light pulse is only just over 1/1000 inch long!! Even if it is just 0.5 joule, I don't think I would want to get in it's way!!

The spark seems very straight and uniform!

I see they use the little semi-spheres for the top in what I think is a HV multiplier in there lab picture.
