The directionality of the laser pointer is good, and the light emitted by the ordinary light source propagates in all directions, and the divergence angle is large. In contrast, laser light has a smaller divergence angle and is emitted almost parallel. The light emitted by the laser is polarized light with a fixed direction. A simple case can express this intuitively: high power laser pointer water does not refract. Among the various lasers, gas lasers are the most prominent in directionality, followed by solid-state lasers, which are less advanced in this regard. Be careful 30000mw laser pointer, please don't use the laser pointer as a toy! Some time ago, Chinese experts conducted an on-site experiment to teach people to distinguish between true and false. Among them, the expert service group of the People's Livelihood Quality Laboratory started the experiment with a blue laser pointer on the spot. Under the irradiation of the blue laser pointer, it could actually light up a game.
Green laser pointers have attracted the attention of many countries
Laser as an excellent light source, green laser pointer began to enter more and more cutting-edge application fields. Many countries are committed to building the world's most powerful lasers, or opening up new directions for human energy; light waves are made up of countless photons. The light quantum emitted by the high-power laser pointer is consistent in wavelength, frequency and polarization direction due to the resonance principle, which makes it have a very strong interference force. We also commonly refer to laser light as coherent light. Precisely because lasers are much more coherent than ordinary light sources. The use of a laser as a holographic light source is also a feature of good coherence. So what is the development level of China's laser technology and green laser pointer weapons after 30 years, and how high is the level of information technology? Because of confidentiality, it cannot be used to analyze accurate data. However, the domestic official media's report on a late national treasure-level optics expert surprised the outside world for the first time at the performance of China, the world's most powerful laser pointer, in developing laser weapons.
Since its invention, laser technology has been widely used in the industrial field. From small "tailor-made" to large "spaceflight", laser light sources have shown that traditional technology cannot match. In addition, lasers are entering the microscopic world of DNA. In the future, it may no longer be a dream for us to apply gene therapy to repair diseases; is it really possible for scientists to find that the light can be bent back in time?
