This looks like a more or less normal raw output. Both my 445s have this raw output.

Might be a little shady, considering the c&p text regarding 30s duty cycles in the section after the pictures.

For beaming purposes. If the laser is properly mounted and care taken to ensure nothing significant (trees, airplanes, etc) are in the path, it is considered generally safe to view the beam without goggles. It is otherwise impossible to view a laser beam with goggles on. A bug flying into the...

Actually, is the GPS solution really that expensive? What kind of precision do you need? An iphone 4 can reach sub-10m precision easily in city areas, probably better in an open field with more satellites visible. With a laser you have to get a good tripod/possibly a theodolite too, GPS might...

Re: For sale : NEW 1.2W blue lasers, $120 !! Might consider adding that since it is a buck driver, it will only take 2x 16340 and not 1x 18650 as is normally used in torchlights for this host.

Not sure what you mean by that paragraph. In any case, the "host" linked appeared to be purely a heatsink. If you want a torchlight-style laser, that is not what you want.

Fully agreed. That is why I disagree that the angular separation is the primary reason the beam stops, being that one of your justifications is that you cannot see the beam become longer, and the counter to that justification has been explained in my post above. I suggest that the beam will...

The output is unlikely to change, assuming your laser used a proper driver. What is important is that the battery is likely to be safer if it is actually a proper brand name battery than some cheap relabel.

Regarding cyparagon's suggested experiment that somebody take a long exposure to test the PBL hypothesis, I have found the following data: 1: Keck Observatory Laser Guide Star http://keckobservatory.org/images/blog/Cooper-2-lasers-zenith-1.jpg Unfortunately, due to the uploader of this image...

The picture you gave had no scale. And the link EF posted stated that the PBL could be as low as 100m. In no way is this "1/1000 of a pixel"

You will need a metal heatsink for high power lasers, other than that there is no reason why one cannot make a host using plastic.

Not a good idea to put a high powered laser in your pocket with batteries inside, in case it accidentally activates.

Static electricity can cause the cap to become charged when it touches one of the wires. If this happens frequently the cap may become significantly charged. Shorting it prevents charging due to any reason.

The Chinese on the magazine (third line of text on bottom left, the one with the second half being red) says "China Special Ops Police: Laser Dazzler Rifle" Logically speaking, if you had a weapon the size of a rifle, the only benefit to a military unit over that of a conventional rifle will be...

A nice thick layer of compound is used for maximum bonding & heat transfer Shouldn't the thermal adhesive used be as thin as possible just to cover up all the microscopic gaps in the metals? This is from my experience with desktop CPUs, where a thick layer of thermal paste will have poorer...

Assuming your "obstacle course" has multiple lasers, and they are triggerable, probably unrealistic. 5mW pointers should be visible in a perfectly dark room, but if you are looking for detection of beam $50 is probably insufficient.

I believe most commercial diffraction gratings are made so that the angle of diffraction is far too large to be useful. You are going to hunt them at 100m, so it defeats the purpose if the dots are spread out over a 30m radius.

Try posting a few pictures of your laser here, I am sure the vets can do something.

A phlatlight, being an LED, will have a significant amount of light below 650nm, which will scare the pigs.
