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…
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 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…
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…
The laser pointer is still very dangerous to the eyes
The energy of the photon is calculated using E=hv, where h is the Planck constant and v is the frequency. It can be seen that the higher the frequency, the higher the energy. Can a laser pointer make a laser sword? We know the principle of laser generation, so the question is, can we make a cool…
Green laser pointer with a high quality IR filter protect your eyes
I’m sure all of you reading this have seen or used a laser pointer at some point in your life, or maybe you’ve even bought one online. But have you ever paid attention to the warning signs on your laser pointer or how dangerous your laser pointer can be? Well, I’m here to help keep you and…
The latest development and application of laser rapid prototyping technology
Laser rapid prototyping is a new manufacturing technology that integrates advanced technologies such as CAD, CAM, CNC, laser pointer, precision servo drives and new materials. Compared with the traditional manufacturing method, it has the reproducibility and high interchangeability of the prototype; the manufacturing process has nothing to do with the geometry of the manufacturing prototype; the…
Precisely cut textiles with a laser pointer
The market demand for large-format printed textiles is constantly growing. In view of this trend, many companies have increased their research and development efforts for more effective cutting solutions. Therefore, the focus of attention has gradually shifted to efficient and economical processing technology. A market leader in the production of banners and flags has discovered laser…
Scientists have developed a new type of hollow-core gas fiber laser
Researchers at the University of Bath have developed a new type of laser pointer that can emit mid-infrared spectra with a spectral range of 3.1 microns to 3.2 microns. The research results will bring new applications for mid-infrared lasers. Mid-infrared lasers are currently mainly used in spectroscopy, environmental remote sensing, and explosive detection. This new laser is…
