From rough stone lamps to bronze lamps, and then from ceramic lamps to modern electric lamps, the historical changes of lamps have been marked by the times, and they are also the epitome of social economy and culture. With the changes of the times and the development of technology, lamps and lanterns have entered a…

Laser pointer lighting that is moving into the future
Since Edison invented the electric light, lighting technology has undergone continuous development. After the incandescent lamp, fluorescent lamp and LED era, it is moving towards the laser pointer lighting era. At present, there are mainly two types of LED lighting and laser lighting on the market. LED lighting, namely light-emitting diode lighting, mainly uses semiconductor chips as…
Laser pointer lighting will replace LED lighting in the future
Laser diodes are the future of lighting. Nobel Laureate in Physics Shuji Nakamura and his entourage visited to conduct on-site inspections and technical exchanges to discuss the future development prospects of the laser pointer industry. He believes that in the near future, LED technology will be subject to the physical limit of its luminous efficiency, and will…
The self-cleaning phenomenon of the beam in the multi-mode fiber laser pointer
Single-mode fiber is often used in the construction of femtosecond fiber laser pointer. Its small core diameter is accompanied by strong nonlinearity, which is easy to cause pulse splitting, thus limiting the increase of laser power. Using the space-time mode locking of a graded-index multimode fiber, theoretically high power can be obtained, and the self-cleaning effect…
Scientists combine gas and multi-core fiber infrared laser wavelength
The latest issue of the Journal of the Optical Society of America published the research results of mid-infrared fiber gas laser pointer by researchers at the University of Bath in the United Kingdom. Mid-infrared lasers of 3.1 to 3.1 microns have important uses in special applications such as spectroscopy, environmental monitoring, and explosive detection, but lasers in…
Laser pointer cutting is very fast and accurate
Laser: In a general mechanical workshop, most lasers can cut metal of about 2 cm, but the thickness of the cutting material also varies according to the metal. The melting point and thermal conductivity of the metal will affect the thickness of laser pointer cutting; the advantages of laser cutting machines The reason is that it can…
The laser pointer will form a laser beam after focusing
Waterjet laser cutting is a hybrid processing method, also known as laser microjet. It combines the laser pointer with “fine” water jets, and the water jets (water jets) are accurately guided by a method similar to conventional optical fibers. The laser beam thus realizes the cutting, and the water jet continuously cools the cutting area and effectively…
The machine produces a high-power laser beam
What are the differences and similarities between the waterjet and laser cutting methods? If you want to cut materials, there are many ways to achieve it, using sawing, as well as air cutting, etc., can achieve the cutting of various materials. But these cutting methods are not perfect, so waterjet cutting and laser pointer cutting were invented…
Brief analysis of perforation process before laser pointer cutting
Any kind of thermal cutting technology, except in a few cases, which can start from the edge of the board, generally a small hole must be drilled in the board. In the early days, a punch was used to punch a hole on a laser pointer punching compound machine, and then a laser was used to start…
The laser pointer has such a wide range of applications
The development of laser weapons first began in March 1964, but greater progress was made after the reform and opening up. The “High-Tech Research and Development Program (863 Program)” was launched in March 1986, and laser pointer technology is one of the subjects in the 863 Program. Recently, researchers from the latest issue of “Optics Letters” biweekly…
