That's too bad. I liked him. Hope he's okay. He seemed very interested in learning all he could about the physics and didn't seem to just want to burn something.

I might have deserved that and unless I was there there is no way I could confirm it's possible it got damaged in the mail. I was just saying mine went through hell and back before it damaged the diode. If that was directed at me I assure you I am learning about the dynamics and still have plenty of room to learn. Maybe I could be your apprentice Obi Wan?

This laser was able to set a leaf on fire submerged in water while it was raining! As previously mentioned with the S4X it lives up to it's name SURVIVAL LASER!

Handheld burning lasers are kiddy lasers. Only children are fascinated by that aspect of laser technology. I care much more about exotic wavelengths and highly coherent lab lasers. The "my laser can burn stuff underwater while it's raining" is what I'd expect a kid to say. It is certainly not what people who work with them find interesting.

Burning stuff is fun, as long as you do it safely.

One laser in each hand is safe, 2 in each hand....not so much.

You are the exception, RedCowboy. I don't see you ever outgrowing that. I haven't tried to burn anything in so long I really can't remember the last time I tried.

I do enjoy learning how things work and even dream up new ideas, also a good quality LPM can give you a number, but burning tests do give an additional benchmark by showing how well the energy is being focused over distances.

Burning through a known media or achieving flashpoint is another good test that can be used at distance intervals to see how well the energy is being focused, and with these phosphor pump brute strength diodes getting a decent beam has challenges as beam quality was never in the original design as much as efficiency and total output.

I love a nice tight 660nm beam, and I still love the deep red color, but I don't bother burning with those diodes anymore, or my 532's or even 520's as they are more enjoyable for aesthetics and making a nice tight spot in the far field.

But give me a million dollar sodium star yellow astronomy laser and I won't lie, as much as I would admire the beam, YES, I would also have to fry some stuff with it too. Safely of course.

Default Re: NUBM44 6W+ 450nm Laser Diode

I've never tried popping a balloon with a laser yet, but I have burned some card board with a FAP800 and some wood and a distant plastic garbage can with a NUBM44

Yet, my main interest is in low divergence beams which can travel a great distance without much spread. That can get me into trouble if I hit an airplane with it! I don't shoot low to the horizon due to that possibility anymore.

Oh I can't argue with exotic wavelengths! I would love an orange laser leaning more towards the yellow spectrum not red.
Burning stuff though obi wan....what would someone use a "survival" laser for?
Yes master. I'm apologizing I was over anxious and thinking about the sando on naboo.

Redcowboy, you made me laugh at the ceiling fan but that's not much distance to the roof which is filled with flammable fiberglass.

I might be wrong.

https://www.corvetteforum.com/forums...flammable.html

https://www.reference.com/home-garde...1d0ddf98b6c5a0

Ok I'm admitting it I was thinking about building a real life hell raiser cube that has an infrared laser parameter alarm and begins
aiming a wide orange beam if you break the ir beams,
uses a pinhead voice "STAY AWAY!" and
blast anyone that picks it up with a focused orange beam.

I know master it was sinister and ill conceived and my thoughts betray me.

That was Accutronitis who burned his ceiling fan.
I have planks of wood set up that I can replace if I just must test a laser indoors, also cinder block makes a good beam stop, but because of the smoke and burnt smells I prefer to keep my burning to my workshop or outside in a safe manner.

Default Re: NUBM44 6W+ 450nm Laser Diode



I may leave this post. Some may instantly figuire it out some may not.
It's the scientific calculation to determine how much light makes it to the human brain!

Can't seem to find my other post on beam correction for the nubm44-6w-450nm-laser-diode but I did finally find all the parts I needed. $119.79 without having anything fabricated for it. That's not including the cylindrical lens pair. (((9T))) and working up. THORRRRRRRRR!!!!
