With the development of laser application technology, high-power, high-beam quality laser pointer light sources are required in many fields such as industrial processing, space optical communications, and optoelectronic countermeasures. Generally speaking, the beam quality M2<1.3 is called a single-mode laser, 1.3<M2<2 is a quasi-single-mode laser, and M2>2 is a multi-mode laser. In multi-mode lasers, 2<M2<4 can be…

A major breakthrough in the vertical cavity surface emitting laser pointer
The State Key Laboratory of Optics and Applications (Light-Emitting Chamber) high-power semiconductor laser pointer and their application team have made major breakthroughs in the research on key technologies of high-beam quality and high-power vertical cavity surface-emitting lasers, and their research results won the first prize of Jilin Province Technology Invention in 2015 . Vertical cavity surface emitting…
Research progress of deep ultraviolet all-solid-state laser pointer
Deep ultraviolet all-solid-state laser sources refer to solid-state lasers with output wavelengths below 200nm. Compared with incoherent light sources such as synchrotron radiation and gas discharge, they have high photon energy, high spectral resolution, strong photon flux and high density, and low repetition frequency. Features such as high repetition frequency and multiple operation modes in…
Deep ultraviolet laser pointer light source as excitation light source
The project “Development of a near-atmospheric light emission electron microscope based on a tunable deep ultraviolet laser pointer light source” successfully passed the field test and acceptance. A few days ago, the Dalian Institute of Chemical Physics of the Academy of Sciences issued a paper stating that the national major scientific research equipment undertaken by researcher Fu…
The French Laser Pointer Communication New Trend Orbit System Project Launched
The French company and the French National Space Research Center jointly developed and evaluated atmospheric turbulence compensation modules. This 18-month project aims to improve laser pointer satellite communication solutions by developing a module that compensates for atmospheric turbulence. In order to achieve this goal, the two organizations, with the support of CNES, will concentrate their respective expertise…
Application analysis of laser pointer cutting of metal materials
All metal materials have high reflectivity to infrared wave energy at room temperature, but the CO2 laser pointer emitting a 10.6um beam in the far-infrared band is still successfully applied to many metal laser cutting practices. The initial absorption rate of 10.6um laser beam by metal is only 0.5%~10%. However, when a focused laser beam with a…
Do you know the advantages of metal laser pointer cutting?
The working effect of metal laser cutting machine is generally clear to people who have used it. Many people also appreciate the metal laser pointer cutting machine very much. The advantages of metal laser cutting machine use will not be introduced here too much. The main thing I want to share with you today is the advantages…
Laser pointer weapon equipment anti-missile drone
Among the entire set of anti-missile combat systems planned at the time, the air-based interception system, which launches laser pointer from the air and directly destroys the missile, is the most sci-fi color. Four years after the project was dismantled due to excessive technical difficulties, laser weapons launched from high altitude were prepared again. The difference is…
India will build a laser pointer fence along the India-Pakistan border
The BBC reported that India will build laser fences in more than 40 “vulnerable areas” along the border between India and Pakistan to prevent Pakistani personnel from infiltrating India. An official of the Indian Ministry of Interior stated that India will build a laser pointer fence around the border with Pakistan to prevent Pakistani personnel from infiltrating…
Israel is equipped with new laser pointer weapons to ensure the safety of civilians
Allegedly, the Israeli Ministry of Defense, the Israeli Defense Forces and the Israeli Defense Corporation Systems Corporation announced on Sunday a state-of-the-art laser pointer-guided mortar called the Iron Spur. The mortar uses lasers combined with GPS to guide it to the target and fires 120mm shells. It recently completed a series of tests to prove its…
