New Application of Laser Range Finder

In the early nineties of the last century, several major companies such as Europe and America successively produced commercially available semiconductor laser diodes, which revolutionized the practical application value of lasers. Other types of lasers are too messy in the mechanism of laser generation, which greatly restricts the application of laser due to its large volume, heavy weight and high power consumption. The emergence of semiconductor lasers makes these problems easy to handle. With the advanced technology of semiconductor laser, the price is gradually decreasing, and its application batch and application field are continuously expanding. Judging from the current opening speed, the application prospect is very promising. Semiconductor lasers are small in size, light in weight, high in reliability, high in conversion power, low in power consumption, simple in driving power supply, capable of direct modulation, simple in structure, low in price, safe in application, and widely used. Such as optical storage, laser printing, laser photo-typesetting, laser ranging, bar code scanning, industrial exploration, inspection and measurement instruments, laser flash, medical instruments, military, security, field exploration, building sweeping and marking instruments, laboratory and educational demonstration, stage lighting and laser playing, laser level gauge and various marking positioning, etc. Some common interests of semiconductor lasers make them very suitable for military applications, such as field ranging, aiming of guns, shooting simulation system, blindness, guidance to submarine communication, fuze, security, etc. Because it can be driven by ordinary batteries, it is possible to equip some portable weapons.

At present, the wavelength bands of semiconductor lasers that have been announced and put into the market are 370nm, 390nm, 405nm, 430nm, 480nm, 635nm, 650nm, 670nm, 780nm, 808nm, 850nm, 980nm, 1310nm, 1550nm, etc. In the meantime 1310nm and 1550nm are mainly used in the field of optical fiber communication. 405 nm to 670 nm are visible light bands, 780 nm to 1550 nm are infrared light bands, and 390 nm to 370 nm are ultraviolet light bands. Warning and Application of Laser Safety Precautions Lasers are high-intensity light source radiation equipment. High-power lasers can be used to cut and weld metal materials. Therefore, lasers have serious harm to human body, especially human eyes. Special attention should be paid to their application. There are common classifications and common safety warning signs for lasers in the world. Lasers are divided into four types (Class 1 ~ Class 4). One type of laser is safe for human beings, the second type of laser is less harmful to human beings, and more than three types of lasers are serious harmful to human beings. Special attention should be paid when using them to avoid direct light on human eyes.
