Some people have all the cool toys in their home!
Thanks for sharing the photos. You've got something that many here on the forum have dreamed about owning for a long time. Well done!

A truly Frankenstein monster of a laser! I would set that laser up for safe demonstrations in public to show people its power. Putting a variety of things at the focus to show what happens. Maybe make some You Tube videos. Ballistic Light!
You, sir, are my laser-building hero.

Thanks for such a kind response!
BTW, yesterday I've realigned the resonator and approached the limit of my current system -- 400J of output energy, I've measured it with an energy meter. But on the other hand focusing mecame much much worse and it hardly melts through a coin. But the holes in coins are relatively big, sumetimes up to 1mm or more, if I make a couple of shots in the same place. Is there any chance to make the beam single-mode with reasonable loss of energy? Will a simple diaphragm in the resonator work?

Continuing playing with my laser blaster. Today I managed to penetrate 6mm thick aluminium plate with two shots at 450J output energy. It is quite spectacular -- the beam causes blindingly bright flash of burning aluminium with a huge jet of plasma with a particularly loud bang. Also I improved focusing by reducing the spherical aberration of the lens. The position of the lens affects this aberration. When a curved surface faces the beam, aberration is less significant. This lead to easier coin penetration -- now I need roughly 200J instead of 450 for it.

Nice! Looks like you are having good fun. Now can you please reduce this to a small handheld size and sell it to the rest of us?
A video would be nice if it won’t ruin the camera.

So awesome dude! Be careful and enjoy your hard work. Very, very cool!

Some additional photos of shooting into an aluminium pate. This is very spectacular, as aluminium burns with very bright sparks.

Wow! I hope you keep a fire extinguisher close at hand!

have you tried magnesium?
