... at least one of a few that I ask/respond in.

I have resisted joining this forum as long as I can. I'm just a tech-weenie although I did have training with an industrial CO2 laser (long long ago and far far away) that my employer had bought. I went to the manufacturer's location in SW Wisconsin for the training and got a real education including excimer :tinfoil:The CO2 had 3 20' folded tubes. We used it for cutting slots in metal plates for connector prototypes. The slots could be made as narrow as 0.007" and maybe narrower depending on material & thickness.

But, laser diodes were just starting development. I have been out of touch since, until recently when I may have finally found an application or 2. AKA excuses for new toys.

I will do my searches and have done a little already as I know this is not a new topic here (why I am here). First up is a laser for zapping nefarious critters in my marine aquarium. Things like aiptasias and flat worms are inevitable and are my prime focus. I done the chemical thing; I have done the electric zapping thing. They work when you can get to the critter. Aiptasias are a anemome & like to get into crevices in rock ... always facing away from a side of the tank. I am thinking about using a dentist's mirror to bounce a laser beam off to get into those places so I don't have to disassemble the carefully structured piles of rock.:rolleyes:Currently I have a 90g & 50g tanks so having to shoot a beam thru a few feet of water won't happen, but that dentist's mirror will add some loss.

Second are the flat worms. These guys should be a snap. So far there are few and they are often on the glass.

I wonder if I should be thinking about 2 different lasers at different power levels?

I am glad to see that you all have a good mature forum. I am in many and some for several years; physics, auto, aquariums, guns, computer (collects the most ... uh ... idiots, but also great ideas).

Thanks for the links, a good start & am about to buy from a member.

It figures that there would the high enthusiasm that I see here. I have not even lurked, and I have lurked elsewhere for years! The experience and training that I had with the industrial lasers kind of freaked me, to be honest. Not being able to seen the light at the business end of that 500W CO2 always bothered me. Definitely not a time to absent mindedly flip your finger under the lens to see if it was on!

Then the excimer guys ... totally covered in a protective suit and in a closed room.

Not to mention the extreme ventilation that we needed to take of the fumes from the exotics we were cutting.

I am surprised at how many lasers some people have, but I get it! I understand the fascination. I may become a believer also.

I like my ~2W 445 I tried it on some stuff in my tank. It was alright.

Now I wish I had a 9mm for 3+ Watts.
Been thinking about RickTrent or DTRs assembled 9mm module to just slap in a number of hosts like Mcrouse's fancy goodies.

I know there are some 5+ watt 808 lasers that are more expensive and c-mounts and stuff.... I think ir is boring I like staring at the colorful beams (not the dots though :) ) in all their pure colors, its so unnatural and mesmerizing. I think you would love it. Plus it wont zap your fingers off like a C02!
