In the past, lasers were large, expensive and bulky items that required running laboratories and building entire factories. I remember the first He-Ne dog laser I saw 20 years ago. It was as big as a small telescope and might not be more powerful than the Laser Pointer I hang on the keychain now. Well, no more. Nowadays, it is easy to build a laser on a kitchen table or in a garage, and the investment is surprisingly small. The goal is to enable the laser to carve small objects, such as a piece of paper, a balloon, etc., while still keeping the entire project cheap-even if you don't do it, it's as cheap as $35. "Error. That's it. Most complaints about laser weapons not behaving like real lasers are because their main function on TV is not like a real representation of how real energy weapons work. They are just substitutes for "real" weapons to appease Media regulators set the spectacle to be futuristic, or just enforce Kur’s rules. In fact, the usual “astronomical laser pointer” effect is more like machine gun shooting with tracer bullets (even according to the color of the country, such as Star Wars) and The experience of World War II. Early writers may have inspired this effect.

As a well-trained laser pointer 5000mw safety officer, I can tell you that you cannot use lasers exceeding 1mW! 5mW is the limit in the United States. If you don’t know anything about lasers, it’s best to leave it alone. Even a 1mW laser can burn your retina! The laser is not a toy! Suppose the funny robot in the video randomly aims at the reflective doorknob, and his eyes are reflected.

It can also cause the water in the body to boil, swell and tear the surrounding tissues, just like a high-speed bullet impact. There is also an electric Burning Laser Pointers under development, which ionizes the air so that current can travel along the path of the beam. Ironically, all of these features make lasers more effective than described in most novels, which is actually the main reason why the military developed them in the first place. This is probably the main reason why we are unlikely to see realistic laser weapons in children's programs.
