@uzerzero
probably because the title of the posting alluded to the movie

I can’t believe nobody has quoted Austin Powers yet:

“All I asked for was frickin’ sharks with lasers attached to their heads!”

Now Dr. Evil’s empire can be completed… all thanks to lskor12. Way to go, you’ve now doomed mankind :D

That thing must light cigars like nobodies business.

If you added enough power I suppose you could cause Hydrogen and Oxygen to separate in sea water. Then you’d have a component of breathable air and something for fuel. Or you could put them back together and have desalinated water. I assume power consumption would be at the ridiculous level and what you’d get out of it isn’t worth it. But if you really wanted to use lasers in the process of creating potable water, I suppose this could do it as well as anything.

Oh yeah, and another thing. Highly directional communication between divers would be a good thing too.

Communication would be a great use. This added to the multi color laser that was posted here a few weeks ago would make for a great device to scan liquids in clear containers. Then we’d all be able to bring them on planes again. I’d turn the emitted power down enough that it wouldn’t cause an explosive to detonate. Although, I suppose if the Navy wanted a way to remotely detonate an underwater explosive, this would be it.

Well, the USN has been experimenting with this sort of laser for years, trying to figure out if they can devise a better (more secure) form of real-time communication between subs and surface ships.

Very true Charlie.
I will have to say….
One thing that never stops amazing me is how bright the beam is underwater.

these blue lasers are really pretty, but definitely more dangerous than they look. they don’t seem nearly as bright as a red or green laser, but can do a lot more damage to your eyes. i played around with one several months ago, and caught a few blind spots. all it takes is a quick flash from a misaligned mirror or something. it is a little scary how easy these are to get now. especially when you see the stupid things kids do with their cheap red lasers.

1. turn it into a laser line
2. attach this and a webcam to the bottom of a rover
3. do detailed 3d scans of small patches of sea floor
4. have some good reason why you would do that
5. profit

This would be pretty good at burning out the CCDs in digital cameras. There was an article on Endgadget not too long ago about some Russian billionaire that was using sensors to pick up the auto focus light and lasers to attack the CCD’s in paparazzi’s cameras.

Pointing things out underwater would be amusing

“And over here is the rare black puffer fish”
*foom*
“oh… here are parts of the now extinct black puffer fish”

“Hey bob, I think there’s something wrong with your scuba pipe just here…”
*FSSHHHHHHHH*

Wonder how many fish you could get to follow the dot? hehe
