Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as their working material. Semiconductor diode lasers are the most practical and important type of laser. It has a small size, long life, and can be pumped by simply injecting current. Its operating voltage and current are compatible with integrated circuits. Semiconductor lasers [...]
In recent years, with the improvement of the ecological environment and the increasing awareness of people to protect birds, there are more and more birds. But many problems have arisen, such as damage to crops, damage to power lines and threats to aircraft aviation. For birds, vision is the most sensitive, especially to green laser with [...]
Laser hair removal uses the principle of melanin to absorb heat and emits light of a wavelength suitable for the absorption of melanin in the hair follicles. After melanin selectively absorbs light energy, the local temperature rises sharply, and the hair follicle tissue will be destroyed. This thermal damage can be limited to the target tissue, [...]
With the development of industry, the requirements for automation in production are getting higher and higher, and machine vision technology has been widely introduced into the industrial industry. Machine vision technology consists of a combination of automation and laser technology, which can achieve many innovative and efficient applications. Using computers and sensors to perform repetitive tasks [...]
A problem often faced in the field of large-scale industrial manufacturing is: how to realize processing positioning conveniently, quickly and accurately? With the development of laser projection technology, positioning achieved through laser projection has begun to be used in the field of industrial manufacturing. Industrial laser projection positioning is a marking technology that uses laser beams [...]
A fiber-coupled laser is a type of diode laser in which the resulting light is coupled into a single fiber. In many cases, the output light from a diode laser needs to be coupled into an optical fiber to be able to deliver light where it is needed. Fiber-coupled diode lasers have several advantages: Fiber-coupled lasers [...]
Laser engraving machines use laser technology to engrave. The principle is to use laser heat energy to burn or cause chemical changes on the engraving surface to produce engraving marks. Using a laser engraving machine can control the engraving text, pattern, and size, and the engraving pattern is also relatively fine. Small DIY laser engraving machines [...]
A multi-line laser is a laser source that can emit multiple laser lines. By adjusting the parameters of a laser, it can be made to emit radiation at multiple wavelengths. This new type of laser is called a multi-line laser. The light spot is a source of multiple parallel laser lines. Its emergence has greatly enriched [...]
In order to create varied stage visual effects, the design requirements for stage lighting are becoming more and more intense, and the types of stage lighting are becoming more and more diverse. Laser stage lights are one of them. Laser stage lights are usually an integrated laser system that generates and emits a stable laser beam [...]
Laser is a kind of high brightness and high uniformity laser, which has a wide range of application prospects in architecture, decoration, engineering surveying, interior decoration, etc. The slotted laser is a semiconductor laser device that projects a slotted laser spot, with various specifications and small size, and plays an important light source in machine vision, [...]
