After decades of development, laser technology has long moved from the laboratory to people's daily lives. Whether it is clothing, food, housing, or industrial processing, and then to medical cosmetology, laser light is everywhere, affecting all aspects of people's lives. From the development status of a country's laser industry , the overall industrial manufacturing level can be seen to a certain extent. In 2019, the growth rate of the laser industry has further slowed down. Although some companies have maintained high growth, more companies are facing declines in performance or even losses. Next, based on the performance of this year (revenue scale and market share), select 10 companies that have the most influence on the laser industry and see how they are doing in 2019. 1. TRUMPF Group Founded in 1923, the TRUMPF Group is one of the global market and technology leaders in the field of industrial production machine tools and lasers. After more than 90 years of dev...

Abstract : The current application of laser holography in some scientific as well as industrial fields were introduced. Some strong points and problems existing in the related fields were analyzed. The development trend of laser holography in certain subjects was discussed. That new technology integration, laser holography will be found for more and more application was em-phasized. Since the invention of laser holography, the application field and scope of laser holography technology have been expanding, and the influence on related technologies and industries is increasing. Especially in recent years, with the comprehensive application of laser holography technology and other discipline technologies, laser holography technology It also shows its huge application prospects. Based on this, a comprehensive research and discussion on the application and development trend of laser holography technology is carried out to promote the continuous application of laser holography technology...

In order to deal with "potential threats" such as China and Russia, the United States continues to raise its chips to "sci-fi weapons." The US Air Force Research Laboratory claims that the latest "Self-Defensive High-Energy Laser Demonstrator Advanced Technology Demonstration Program" (SHiELD) successfully shot down multiple incoming missiles during the test. The US Navy has greater ambitions and plans to install laser weapons for the Aegis destroyers to defend against the "China missile frenzy." However, experts say that even if these plans go well, the US tactical laser weapon system will take at least a decade to put into practical use, and it needs to solve a series of problems such as volume, weight, power supply and range. Started testing on fighter aircraft in 2021 The US military's "Stars and Stripes" reported on the 6th that in a series of tests conducted at the White Sands Missile Range in New Mexico, the "lase...

Since the emergence of lasers in rubies in the 19 6 0s, in the same year, calcium fluoride (CaF2:Sm2+) was found to output pulsed lasers. In the second year, pulsed lasers were obtained in ytterbium-doped silicate glass. The rare earth has formed an indissoluble bond. Rare earths have many properties such as magnetism, light, electricity, superconductivity and catalysis. They are one of the most important materials in this century. They are widely used in many fields. As a non-renewable resource like oil, they are valued by many countries. Strategic resources. Since the rare earth was bonded to the laser, the utilization of rare earth in the laser has been deepened. In 1962, the CaWO4:Nd3+ crystal was used to output the continuous laser. In 1963, the rare earth chelate liquid laser material was firstly developed, and the erbium-doped benzoylacetone was used. The pulsed laser was obtained from the alcohol solution. In 1964, the ytterbium-doped yttrium aluminum garnet crystal (Y3Al5...

The largest consumer market for lasers in the world - China China's laser industry market started late,However, with the rapid development of China's equipment manufacturing industry, China's laser industry has achieved rapid development in recent years. China is an active market for manufacturing and industrial laser equipment. Affected by factors such as macroeconomic development, upgrading of manufacturing industries, and support of national policies, China's industrial laser industry has become one of the industries that are highly concerned, and the market is developing rapidly. In 2015, China replaced Europe and became the largest consumer market for lasers for the first time. In 2018 The market grew to around US$2.8 billion, accounting for 29% of the global market.

How is the white laser produced? White laser principle We all know that lasers have monochromatic properties. A laser corresponds to a wavelength that produces a color. The picture below is the color distribution of lasers of different wavelengths. The white laser is not directly generated by the laser machine. It is synthesized by red/green/blue laser. e.g. Below  CivilLaser ‘s white laser, There are 3 kinds of lasers inside, and then they are concentrated by the lens system to the same light exit, forming a white laser. White laser RGB Laser system (Red / Green / blue can be used alone) White laser / RGB laser module

The difference between single mode laser and multimode laser The beam quality of a  single-mode laser  is good, and the spot is round. But many wavelengths of laser can not do TEM00. Especially high-power lasers, multiple LD-synthesized lasers, they are multimode lasers. Got to  CivilLaser .com find more single mode laser and multimode laser.

Laser positioner — How to choose the laser output power? Dot laser, line laser, crosshair laser , etc. Laser modules are widely used as positioners in industrial production. Many customers don’t know how to choose the power of the laser. The power is too small for the operator to see the laser; The power is too high, the laser is too dazzling, affecting normal work. So how do you choose the laser power at different distances? CivilLaser  take the red light as an example and sort out a table for your reference. Laser module — The relationship between the power,brightness and working disance. OUTPUT POWER BRIGHTNESS LEVEL BEST WORKING DISTANCE DESCRIPTION <5mw Micro Light < 0.5 meter 1. In less than 0.5 meters. 2. Under the weak light environment. You can see the laser beam. <10mw Low Light < 1 meter 1. In less than 1 meters. 2. Under the weak light environment. You can see the laser beam. <100mw Middle Light < 3 meters 1. In less tha...
