It is understood that this year's CCTV 3.15 party experts have a laser pointer Infraot with a power of 4500 milliwatts. The moment the laser launch is turned on, a dozen balloons are lifted up. It took a while for the laser pointer to aim at the dark clothes and found a hole in the clothes. The infrared red laser pointer
shone on the match head, and after a while, it burst into flames. The power of the laser diode is mainly used to generate a single-wavelength excitation resonator beam, that is, the intensity of the laser pointer. For lasers, power is an important indicator of energy released per unit time.In March of this year, the General Administration of Quality Supervision, Inspection and Quarantine issued the "50mw Laser Pointer, Laser Gun Children’s Product Quality and Consumer Safety Risk Warning Reminders", stating that children should not buy laser pointers as toys and consumers should avoid using blue laser pointer
to illuminate human eyes. , Skin, clothing and other places. The General Administration of Quality Supervision, Inspection and Quarantine reminds consumers to check the packaging, try the product or confirm with the seller whether the toy laser is confirmed when buying children's toy guns. Consumers are advised not to buy toys with laser aiming gun, laser shooting function or children's function. When purchasing related products, you should carefully consider whether it belongs to the category of laser radiation. It is recommended that you use more laser toys and stop immediately.Laser difference in the laser market
Compared with the previous green laser
market, laser pointers have developed towards higher output power and multiple colors. At the same time, a large number of manufacturers and distributors withdrew from the laser pointer market, which made laser pointers a mass market. The sloppy laser pointer is also significantly lower than the real laser crystal. Any time you choose a laser pointer that people can see clearly and observe, it is the real purchase. The quality of the laser crystal is particularly important. Low cost is the reason for the low price, so the quality of laser crystals manufactured in large quantities is poor. Although the price of sloppy laser pointers is low, there is always danger in the beginning. People still choose sloppy laser crystals. In the same output power range, a sloppy laser pointer is not as bright as a real laser pointer.The working principle of the green extreme laser pointer
To understand this, we must use the infographic (below the text) to carefully study the principles of semiconductor lasers. Every extreme high powered laser
pointer needs a power source, usually a simple battery or a rechargeable battery, some of which can also be charged via USB. The color of the laser beam produced depends on the semiconductor material and is always red in the most cost-effective version of everyday hands. The green laser pointer requires a final assembly.
