Good Lordy... Laser rust removal!
 

Wow just wow. It takes a lot to impress me but...

I think this is the link for the equipment:

1000 Watts High Power Laser Systems - cleanLASER

What a fantastic application for laser energy! This is very cool! I want one!!!

That's freaking awesome!

Very cool indeed...

Incredible!

Woo-who! I sure could use one of those this week!

Thanks but any idea on how much this system would cost?

I'd imagine it would be very expensive.

$275,000.00 usd

^^^ Actually not as bad as I thought.

You could build a very successful business around this device.

Not for the DIY... https://www.reddit.com/r/LaserCleaningPorn/comments/2w6lie/cost_of_laser_systems/

A reddit post from over a year ago asked something similar and someone contacted the system manufacturer. At that time it was:
$380,000 for the 500W and $280,000 for the 300W.
This place, put their demo 2012 CL500 (500W) up for $275,000 and a CL100 for $145,000.

That is really incredible.

What would it do on sheet metal?

The examples shown are relatively thick, especially the second video.

I imagine there has to be some heat input. Heat input = potential warping...

What would be cool is to mount these onto fricking sharks... ... And use them to remove fouling from boats or marine structures.

That was my first thought too...thinner metal like the body of a rusty vintage car...it could warp from use if it's generating heat.

If the pulse duration of the laser is short with a long thermal recycle time it would be ablating the rust vs. burning it off hence less heat generation. Hitting high peak power at a very short pulse would be ideal.

I wonder what type of laser it is...too expensive to be a diode. Maybe a micropulsed CO2?

Ugh...I know too much about lasers.

Also what happens when you hit bondo?

If it takes off paint and undercoat...... it would be a restoration dream.

Since "incredible" has already be used, I will go with INCONCEIVABLE!!!! Brilliant!

Great for manscaping too :D

Only if a Sicilian is involved!

There's gonna be a lot of happy junior enlisted sailors when the navy adopts this technology!

looks like a lot of air is blown over the surface to control heat issues
