Ehgemus made another host for me. I added the chrome tube and cone with lens. Has a NDG7475T 1.4 watt output 520nm green laser diode in it. The output is an uncorrected beam, because of this the beam is a rectangle shape, but I will be adding corrective optics to it later to round out the beam more.
Why the huge lens? With a five inch lens the divergence is so low for 10 miles and greater distance this 1.4 watt output laser can theoretically produce a brighter spot than a 1000 watt 3.6 mRad divergence laser which is the typical divergence for this diode when used with a G2 lens (of course, a 6 mm G2 lens wouldn't survive that much power). At one mile distance the spot should be brighter than a 400 watt laser, at a quarter mile as bright as a 100 watt laser, at 500 feet a 20 watt laser. I'm assuming a best case with the above figures, but even if I am off by 25 percent across the board, due to its low divergence this laser will still produce an awesomely bright spot many miles away making the typical 1.2 to 1.5 mRad laser pointers more like flashlights in comparison.
Strange reality isn't it, that a laser pointer with a big lens like this which looks like a flashlight can do that. I'd like to do this same thing with a 100mw single mode laser diode, using one of those in this host would produce a much brighter spot at distance, although the beam itself less than impressive
Above beam shot photo taken after swapping out the 4 inch lens with a larger cone and 6 inch diameter lens. The lens is larger than the 5 inch diameter aperture, because of this it overhangs the rim. A small amount of rubber cement keeps the lens secure.
This monster takes 2 X 32650 batteries, plenty of capacity
