LiDAR is one of the key technologies for robots and autonomous cars to perceive the world around them, but today’s LiDAR components, such as lasaer pointer and sensors, are typically of large sizes. Laser radar innovator Voyant Photonics has come up with a different idea, with a system that can fit right on your finger,…

The laser is regarded as one of the greatest inventions of the 20th century. With the end of the three industrial revolutions, the laser will be the key to lead the fourth industrial revolution. The appearance of laser greatly promoted the development of industry. Laser has become one of the most advanced and widely used…

Recently, military science and technology service company of Harbin xinguang photoelectric technology co., LTD. (hereinafter referred to as the “xinguang photoelectric”) published for the first time publicly kechuang board listing prospectus, plans to raise funds 87561.66 ten thousand yuan, mainly used for integrates light product batch production line upgrading and precision machine parts manufacturing, farce…

Laser fine engraving technology has the characteristics of fast marking speed, clear and beautiful handwriting and graphics, safe and pollution-free, and does not affect the quality of the base material. It has triggered a revolutionary change in the diamond jewelry industry, and is replacing the traditional engraving method with its unique advantages. Relying on the…

Since its invention, laser has been widely used in manufacturing, testing, medical treatment and other fields by virtue of many advantages such as monochrome, good direction and concentrated energy. In recent years, scientists have discovered a more exotic laser, the femtosecond laser. Femtosecond lasers are the shortest pulses available in the laboratory. Femtosecond lasers can…

Laser engraving machine laser engraving machine will also be a laser marking machine. In the use and maintenance of the need to master the method and careful maintenance, so that the machine can play a more stable role. 1, the good grounding laser power, laser engraving machine machine tool bed body must have a good…

In the past few decades, Nd:YAG pulsed lasers have been a major force in material processing, and many of the machines have been in use for more than 30 years. Among them, pulsed lasers with wavelength of 1070nm are most widely used, such as medical devices, aviation, electronics and so on. However, the laser still…

The CO2 laser, invented by c. Kumar n. patel at bell LABS in 1964, is an ancient technology in the rapidly changing photoelectric industry. Despite its long history, CO2 laser technology continues to thrive in the market thanks to its unique wavelength, power and spectral purity. Because many natural materials and synthetic materials have a…

Quantum cascade lasers (QCL) have long been considered as a natural concept of terahertz devices. Like many lasers widely used in visible to infrared wavelengths, quantum cascade lasers are based on semiconductor materials. But quantum cascade lasers work entirely differently than the typical semiconductor lasers used in barcode readers or laser Pointers. In short, quantum…
