The main use of lasers in astronomy and stargazing is to help identify constellations, stars and planets; Despite a growing number of complaints from federal authorities, the device has reportedly been targeted by malicious and irresponsible laser owners. It shouldn't even be said, but we hate seeing these types of stories... Especially as they are reported more and more. We were talking about pilots reporting an increase in laser interference during takeoff and landing. Last year, nearly 3,900 incidents were reported, more than 10 times the 384 reported in 2006. The word laser is actually an acronym for "amplification of light by stimulated radiation." Simply put, a laser is a beam of light, a beam of photons moving in the same direction. The strength of any green laser pointer depends on the amount of energy it produces, usually measured in milliwatts. Because these laser Pointers come from far-flung foreign countries, they are often missed by the FDA's required safety hazard stickers.
Why people feel pressured to do this, we're not sure. We're talking about 20mW green laser designators that cost less than $10. You'll find more powerful models, such as the 300mW green laser pointer for under 60 euros. Yes, these are very attractive prices, but have you ever wondered how they can offer these products at such a low price? Cheap green high powered laser emit more infrared light than green. This is very dangerous because the human eye cannot see infrared. For bright visible light sources, your eyes are naturally programmed to turn and look away, or to self-protectively close. However, if the light is not visible, this natural reflection becomes unnecessary in the case of infrared light. Blasting the brain with lasers is a booming technology in neuroscience. A postdoc is shining lasers into the brains of mice every day for medical research. However, he is also well aware that the continued presence of high-power lasers can cause significant damage to the brain.
