German laser pointer
If you look at the point of light of a laser pointer, you will see an optical effect called "spotting" or "grain". The light spots do not appear uniformly bright, but rather grainy, as if "flashing". You can see this effect especially clearly if you use a lens to widen the light and direct it onto a matte surface. This granulation is caused by disturbances in the eye caused by the reflection of coherent high power laser pointer light on the non-ideally smooth surface of the irradiated body. This results in different path lengths for light and creates sites of constructive and destructive interference on the retina, manifesting as light and dark spots.

Make sure to buy a good quality laser pointer
When choosing a green laser pointer, the first thing to do is to ensure reliable quality. Every laser enthusiast wants to get a good laser pointer at a great price. Even though the market is flooded with shoddy laser pointers, people don't despair. Qualified laser pointers don't have to be expensive, and reputable laser suppliers offer laser pointers in a variety of output powers and colors at favorable prices.
Due to their high power output, powerful jets pose a significant potential human danger if they fall into the wrong hands. Powerful beams can cause serious damage to human skin and eyes, so active measures should be taken when using high-power green laser pointers. Wow, I would say no one would deny their commitment to their own presentation tool - a green laser pointer in the form of a pen. The cost of the laser diode directly determines the price of the manufacturing cost, which is why inferior laser pointers are sold at such low prices. Low-quality laser pointers have a lot of scarcity and danger. A poor quality laser can burn out in a week or less than a real laser. Poor quality laser crystals burn out in a short period of time and emit infrared light that is very dangerous to the human eye until it is too late.
