How powerful is the laser pointer?
The power of the laser pointer depended on its power. In general, low-power laser pointers (0.4 to 1 millivolts) generally do not cause harm to the human eye and skin if the exposure time is not long. However, the more powerful laser pointer (3-5 millivolts or more) can cause damage to the human body and can even ignite matches, firecrackers, and paper. Some laser pointers had a power of up to 100 to 300 millivolts and could instantly ignite objects. In addition, the laser pointer was the most harmful to the eyes because the eye was a lens. The parallel beam of the laser was focused on the retina through the lens of the eye. The energy density of the light increased by dozens of times, which could cause the retina to burn through and cause permanent damage. In short, the power of the laser pointer could not be underestimated.

Top 10 most powerful laser pointers
Information about the "Top 10 most powerful laser pointers" was not found in the search results, so I don't know which brands are the top 10 most powerful laser pointers.
How is the laser freckle effect? Will it rebound?
The effect of laser freckle removal was relatively ideal, and generally it would not rebound. Using the laser freckle method, the energy of the laser could break the black granules without causing damage to the skin cells. Laser freckles were only temporary. If one did not pay attention to sun protection or ingest light-sensitive foods in their daily life, the plaque might reappear. Therefore, it was important to maintain a good attitude, choose a regular medical institution for treatment, and pay attention to daily sun protection.
How to draw laser effects in comics?
You can start by using bright, intense colors for the laser. Make the lines sharp and maybe add some glow around it.
The difference between laser freckle removal and laser
There were some differences between laser freckle removal and laser freckle removal in terms of principle, equipment, and effect. Laser Freckle Removal used laser technology to emit light beams of specific frequencies to selectively destroy the black granules, thereby reducing or fading spots. Laser freckles also used laser technology, but different frequencies could be used to adapt to different types of spots. Laser freckle removal usually used Q-switch laser equipment, such as the Nd:YAG laser. There were many different types of laser devices that could be used to remove freckles, including carbon dioxide lasers and pulsed dye lasers. Both methods can effectively improve the spot problem, but the effect may vary according to the individual's situation. Laser freckle removal was usually able to more accurately target the dark spots, so it had a better effect on deeper spots. Laser freckle removal could be applied to a wider range of spot types, and the laser's wavelength and energy could be adjusted to meet the needs of different patients.
How much does laser gravel cost?
The cost of laser stone crushing was about 2000 to 25,000 yuan. The specific cost depended on the surgery method, the size of the stone, and the hospital's charging standards. The treatment cost of flexible ureteroscopy and holmium-laser gravel was generally about 20,000 to 25,000 yuan, while the cost of other surgical methods was about 2000 to 5000 yuan. Different levels of hospitals and different medical insurance conditions also affected the cost. Therefore, if you need to perform laser gravel surgery, it is recommended to consult the local hospital to obtain accurate cost information.
How are laser swords in science fiction designed?
Well, laser swords in science fiction are designed in really cool ways. They are made to look futuristic and badass. The hilt can be made of various high - tech materials. Some are shown with buttons and switches on the hilt for different functions like powering up, changing the blade mode. The blade is designed to be able to cut through almost anything in the fictional universes, so it has a very sharp and intense look to it, like a concentrated beam of pure energy.
How are laser weapons depicted in science fiction?
Laser weapons in science fiction are depicted in diverse ways. They can range from small, concealable devices to huge, planet - destroying cannons. In many sci - fi universes, they are a staple of advanced civilizations. For instance, in the 'Star Trek' series, phasers are a type of laser - like weapon that can be adjusted to stun or kill. The way these weapons are shown gives an idea of what the future of warfare could potentially look like, with their clean, energy - based attacks compared to the more primitive ballistic weapons we have today. They also play a role in creating a sense of the high - tech and futuristic settings that are characteristic of science fiction.
Wuzhu Laser
Wu Zhu's eyes had laser energy and could destroy objects by shooting laser light. In order to prevent hurting others, Wu Zhu kept his eyes covered to avoid accidentally shooting the laser. His eyes were extremely powerful and could easily destroy everything. In the plot, Wu Zhu's laser eyes were used to kill the Qing Emperor. However, the search results didn't mention why Wu Zhu had used the laser eye at the end or how this decision would affect the development of the plot.
