Speaking of, i dont know if it matters to you or not (maybe you like it? ) but some chinese sellers on both aliexpress and ebay are using your picture (you're literally in it) for their product images, ill see if i can find some of them...They quoted my conversation with my boss on FB.
"it operates in the 460nm range…crazy that these are available! I’m running it on a big lithium polymer battery pack that can dump over 250A at 7.4V. It’s great at lighting things on fire from a distance!!"

I am away from this laser right now, but next time I have the chance I'll try to get some pictures. I doubt I'll be able to do it justice... it is like holding a bolt of lightning at night.

That's really cool!! I need to find an elevated area to shoot some laser beams long distance with. This is hard to do in IL...One example. There are many more such images on the interwebs.

There was a site I had booked marked on my old pc which crashed. I tried looking for that site today, but could not find it so far. Anyway, what I liked about it was they not only had photos of the beam pointed slightly off center of their camera, they also had close up photos of the spot where the beam terminated. A friend was at that location taking those photos. The distance as I recall was 17000 feet. It was interesting to see how bright and large the spot size was at that distance. We always see lasers from the user point of view, it would be interesting to to do a comparison between your 40w and a typical 5mW green or blue laser if you've them. I do not remember the laser's power rating. A good tripod or telescope mount will make pointing steady.
There was no duct tape used...just lots of electrical tape.Maybe I'm confused (or hard to impress), but what I'm looking at is a a bunch of 5watt diodes 'duct tape' together.
In terms of burning stuff, in the second part of your video the 6watt pointer ignites things about as quickly as the 40watt unit. That's because the beams are so spread out they don't combust any faster. That's where your college engineering professor smacks you in the back of the head and says 'get it?'.
How about using optics and at least trying to collimate the 40 watt unit? That at least might be cool.
