Solved! Thank you!

That's the problem, I don't see a set screw other than the one I have photographed. The rest of the host is just metal all around. I'm pretty sure it was already this way when I bought it too. Only idea that I have left is that there are 4 grooves around the front of the laser, next to the set...

I have already located the set screw, and it's shown in the first two images in OP. Problem is that I'm not sure how to access it, as it's behind solid aluminum and I don't see a way to move the set screw outwards. I'm comfortable with soldering and also have a build soldered from parts, I was...

This is the build I have https://laserpointerforums.com/threads/sold-2w-445nm-laser-in-highly-polished-host-the-razor.72528/ , but the mounting hex screw for the module seems to be inaccessible and I can't take it out to fix whatever went wrong. Original seller (lazeerer) has long left the hobby...

Re: the flashing, it is either due to overheating or insufficient current to the driver. It is usually caused by a poor heatsinking/poor connection from the driver to the battery.

Will order once they are up and LPMed I guess.

Will you do international shipping to UK? Am interested in 532, 405 ones and maybe 650s.

I am surprised nobody has corrected this. The 200mW laser's dot size is unknown, and hence it is completely possible for it to have higher energy per unit area than sunlight. In fact, if you assume 1kW/sqm, as long as the laser's dot is smaller than 2 square centimeters (almost always true for...

I don't think satellites can be damaged by ground-based lasers. Satellites orbit at hundreds of kilometres (minimum ~200km), and a beam from a handheld laser will have diverged far beyond any damage threshold.

That link looks extremely suspicious. Firstly, the wavelength makes it a CO2 laser. The pdf appears to claim that the CO2 mixture is pumped by "compressing" it and making it "flow at Mach 6", using some technobabble. It then states that the laser rifle produces 600J pulsed shots, at 2kW power...

The actual laser things are pretty accurate, even down to the divergence level. The spot would indeed be that large to within an order of magnitude, considering divergence for average lasers differ by that much. I am only irritated because he advertised WL, it made him look like a shill (I...

Laser Pointer FUUUUUUUU I was quite impressed with Randall Munroe's degree of research in the subject matters that he discusses in his webcomics, until today.

They would be likely to blind themselves before they blind their pet though.

Applying a coating would mean covering the entire cockpit window with material resembling that found in laser goggles. This would reduce cockpit visibility as well as make the pilots literally colour blind. It is equivalent to asking everyone to wear bulletproof vests because they are at risk...
