How to build a homemade laser pointer?
The laser pointer, also known as the laser pointer, refers to the celebrity pen, is a visible high powered laser designed to be removable and easy to hold, and the laser module light emitting diode is processed into the pen classification emitter. Common laser Pointers are red light λ= 650-660nm, 635nm, green light λ=515-nm, 532nm, blue light λ= 445-450nm and blue violet light λ=405nm. In addition to first-class clarity and near-zero humidity at night, if you shoot a green laser pointer into the sky, you can track the beam along hundreds of meters. It looks like a beam of light to you and to anyone standing around you and it's actually very easy to show someone a particular object. Just factor in the laser and say, "There it seems!"

When it's easy to hit an object, some of them bounce off again. In addition to the fact that children are involved, if an extremely mild beam hits an object that is moving particularly fast, it can cause electrons to vibrate violently, which in turn can really slow them down -- a process known as a radiation reaction. The radiation response is thought to occur in one of the most intense environments in the universe, equivalent to circular black holes and quasars, which may be supermassive black holes surrounded by fuel.
