Before we dig into this morbid and sinister question, we must stress that we do not give you a step-by-step guide to building a deadly laser, nor do we condone the use of a laser pointer for anything other than its intended purpose. Seriously, these things are not toys. An interesting thing about lasers is that you can harness the power of multiple high power laser pointer beams to create a single, higher-powered beam. In theory, this seems simple enough, but let's step in and say it's not as easy as it sounds. To do this, you need to make sure that all the bars are perfectly aligned and that no intersections are not. At that level, though, the danger of infrared light alone is hardly lethal. Infrared is the most dangerous because it's invisible, so your blink reflex won't work until the retina starts to burn.
While this may be common sense to many, we just need to make sure it's clear: blue laser pointer are not toys and can be very dangerous. Regardless, knowing that lasers can permanently damage your eyes, pop balloons, and set fire to tons of different things, we decided to find out how many lasers would be required to be lethal. LIMITED 15 MINUTES - When using a laser pointer on your cat, the most important thing we do is make sure your cat is safe. Therefore, the automatic laser pointer is limited to 15 minutes. That means don't forget to turn off the laser pointer and come back after an hour while your cat is still playing! We found that a laser pointer could be focused by a lens to produce a more powerful beam under the right conditions. We also found that high-power lasers passed through the human eye can burn and melt their brains. But how big should this powerful laser pointer device be?
1) It is a commonly known laser pointer;
2) It runs on battery;
3) Designed or intended for handheld use;
4) A coherent beam of optical radiation with low divergence can be generated;
5) Power greater than 1 mW.
