LOL - These lasers would remove a tattoo by completely vaporizing the skin, and tissue containing the ink OUCH!Originally Posted by Paulo
I completed a brief series of videos showing the eradication of Aiptasia, GSP and Xenia along with the cutting of a "DMZ" between battling Montipora.
I'll post them as soon as the uploads are processed by YouTube.

As far as a mount, what about a suction cup that has a bracket attached to it it that comes up a couple of inches that will swivel allowing full positioning of a pen laser. If you market it, it must be small, compact and easy to use. Just a thought but you may want to get a patent pending....
Here are a few short videos (HD) showing how different corals respond to the laser. The Montipora were lasered through glass - the rest through acrylic.

Crazy!! The fun I could have on a Saturday afternoon.

Big hand for CSQ!!!
Awsome job Tom-
Looking forward to the updates in a couple weeks.
Thanks Chris - It's getting interesting

In following up on a number of the tests, I'm finding that Xenia seems to be among the most laser-resistant and I suspect it might be associate with it's lighter color and greater mass. I've found that in smaller patches, I'm able to completely destroy it in a single session, with larger groupings requiring multiple laser sessions.
The Monti test was perfect...
It vaporized all the tissue in the lased area without hurting any of the surrounding polyps or tissue. All that remains is the bleached with skeleton.
Here are a few thoughts I've formulated since starting these tests...
- More is Better - Although expensive and requiring the maximum safety precautions, I think using lasers with the highest outputs are a plus. This is also important as it appears that many lasers being sold often fail to meet the advertised output. Better retailers will also provide (for a fee) a "power certificate" detailing the actual performance of the laser and diode being purchased.
- Cooling effect of water - Because were using laser to superheat and destroy pest with the aquarium, were subject to the cooling effect of the surrounding, moving water.
- Planula - One of the primary pest being targeted is Aiptasia. When attacked, it can release free-swimming larva called Planula. If not destroyed, these can go on to create many hundreds (if not thousands) of new pests. In theory at least, we want to generate the maximum heat possible, in the shortest time possible to destroy any Planula released.
- Transparency and colors resistant to laser - Some of the pests being tested seem more resistant to destruction by laser. These include Xenia, a much lighter (almost white colored) soft coral that is very fleshy and seems to recover from even extended lase sessions.
- Use in destroying blue/green algaes - Many algaes also seem resistant to laser destruction. While the sizzling and popping sounds are easily heard during lasering - they seemingly are able to regrow.
While 1800mw 445nm is proving to be extremely effective, I'm currently researching the use of a different spectrum laser that might provide even better results over the 445.

For anyone questioning the potential damage a 1000mW laser can do - Here's a story about a laser hobbyist inadvertently struck in the eye by a 1 watt 445 nm, blue laser (less powerful than what many are using in aquaria.) Even though the laser struck his eye for only about a second (as it rolled off a table), it resulted in burns to his retina requiring surgery (at the time time this was written, the outcome of surgery was still pending.)
To give you a sense of the damage to his eye - Here's an image of a healthy retina...
Here's the image of the retina damaged by the laser...
Had he been wearing appropriate eye protection, no damage would have resulted.

Ok I'll stick with my kalk and vinegar. Yikes!!
I agree! I don't want to negatively get this topic off track, but it seems like the risks strongly outweigh the benefits here...
