Most people like the 10000mW laser pointer. The green laser pointer is a good burning, astronomy and academic project. If you want to buy this green laser pointer, you should first consider our green laser pointer. The green laser pointer is basically the same as the ordinary lamp, both of which are electromagnetic waves, with a propagation speed of 300,000 kilometers per second. However, the behavior of laser generation and light emission is different from ordinary light, which is non-divergent light generated when a material is excited by energy with the same natural oscillation frequency. So, what is the difference between laser and ordinary light? In addition, many people may encounter such a problem: the way to use the star pen during the day is correct, how can it come out "out of power" at night? The principle is to use a 200mW starlight laser to generate: the semiconductor crystal uses a 808nm laser pumped laser, and then passes through a multiplier.
First, laser light is excited, while ordinary light is composed of photons. The red laser pointer is relatively easy to make, with a wavelength of about 600 nanometers, mature technology and mature semiconductor processing equipment. The wavelength of the green laser is around 530nm. This is a green laser pointer with high price and low power because the technology of band semiconductor high powered laser is not very mature. Personally think that the power of 200mW to 500mW is more appropriate, and the special sunlight can be felt in the room with the power of 500mW or more. The price of laser pointer 1200mW laser has stable main and auxiliary bandwidth bandwidth, and the price is more expensive, but the human eye cannot distinguish the difference in this bandwidth. Among them, the economically bundled friends choose the power below 200 milliwatts, and the price of the laser pointer is more than a few hundred dollars. . The powerful violet laser has been used as part of home care. The nurse chooses the laser pointer mounted on the spectacle frame or hat. This easy installation of the laser pointer on the glasses allows patients with mobility impairments to point out letters, words or other content on the communication card. Usually very low voltage and laser pointer IIIa can perfectly meet the needs.
