That’s a nice idea for a next project, I will think about it. If it succeeds I’ll of course will have to post it on another kind of forum.

Edit: I did some research and if I am going to try it, I will probablyuse Thorium instead of Uranium. Not only it is more safe but it’s also much easier to get then Uranium.

Yes, go ahead. Kill yourself as you like. But try to not harm others.

Really, when I watched your video how you shoot at the target in front of your window, I was glad not to live in your neighborhood. I don't want to imagine how often this beam went out of the window, probably hitting the house in the background. You don't even seem to have a clue that your "toy" is emmitting dangerous radiation, when it is suposed to be off. And other than the fictive Star-Wars Lightsaber, the beam does not stop within a meter, but goes on thousands of miles in a tiny fraction of a second. There is no "safe distance" for a 40W Laser. There is a good reason why these are mounted in a shielded environment.

If I eventually meet you in person, I certainly won't hand you anything as powerful as a box of matches because smart as you may be, you don't seem grown up enough to take the responsibility that goes with handing powerful things.

Window looks shut to me , Beam isn't going to pass though it in any reasonable time , Though aiming it near a window isn't the best idea regardless : /

Op - What's the beam size like ? On my 60W the beam was around 1" in diameter about 22 feet away , I did do a semi portable 20W Co2 laser a while back , needed the DC to AC to make it fully " portable " , Nice work on the build .

Cloudray Laser sells a beam combiner mirror used for aiming. They do not use the word dichroic, but it is the same technique used in most RGB modules to mix beams.

There must be leakage from your high voltage supply to produce an output when it isn't triggered. Your trigger is leaking, or was it faulty and closing when you thought it as open?

Hello,

I dò not like lasers that I can not see, every reflection on a metallic surface can be harmful (the same with visible lasers) and with bad luck you probably ask, who switched the light off?


best regards

For those who are talking about this project in a negative way.
Everything in this world has risks.

There's a difference between accepting reasonable risks and being carelessly recklessly.

All of the commercial CO2 power supplies I have seen have built in ports for analog control of power and one or more interlock ports that can be used as switch/trigger.

Obviously I agree. Sometimes you have to burn yourself to discover something is hot. If you injure someone else, that is where I'd draw the line.

Haven't you ever had a dream where you hurt someone, break someone where by you can't fix the damage you have caused and for that you feel terrible ?
That's your subconscious mind warning you to be careful or else.
It used to be in America that if you caused someone grievous bodily harm that you would not be criminally charged if it was an accident because it was thought that you would punish yourself mentally for your terrible mistake, but as we realized that some people are careless and lack basic human empathy and remorse that we must make everyone criminally liable for even mistakes that cause bodily harm to another, granted accidental injury typically carries a lesser sentence than intentional injury, but causing harm to another carriers a severe criminal penalty for a reason, except of course and justly so in the case of self defense, sadly in some countries and even some US states our God given rights to self defense are not justified and that causes a whole new set of problems, but it all stems from people not taking the safety of others seriously, but in time as a society becomes more intelligent a balance will be achieved and people will learn to teach their young to respect others and avoid causing harm unless it is necessary to prevent harm from a careless or dangerous person.

---edit---

What I am saying is I draw the line BEFORE hurting someone else, we must or face the consequences except of course in the case of justified self defense.

A high school kid playing make believe creating meaningless and pointless homemade device has it's limits, especially when the result is a very dangerous to others device. The limit it is when you are a danger to yourself and/or cause harm to someone else.

I don't see the significance of being able to turn on a 40W CO2 laser with a cardboard box covering it and burning a sticky note and calling it a death ray.-- is a demented fantasy for attention it seems.
He could do a lot better with a box of kitchen matches burning and death and destruction-wise. lol
How is that distinction as a human being--is not building a laser muchless a "deathray"is just applying electricity to a CO2 tube.
Sound like a high school kid that has nothing to do and nobody to do it with who is an accident looking for a place to happen to me.

The laser also burns a little when it’s not triggered, wich I had to find out the hard way: I was setting up a burning target when suddenly smoke appeared on my shirt 😅. It isn’t a big problem though; it burns much stronger when triggered.
To me a problem such as lasing when the device is switched off/not triggered is a STOP AND FIX IT NOW kind of problem.
I don't have any issues with the kid building a laser, but operating it without fixing the above mentioned problem shows a lack of caution that's very concerning, it's like driving your car without any brakes, why not be patient and fix the problem before driving any further and risking an accident ?
