How to cool the laser? Analysis of laser pointer cooling principle

Everyone knows that the laser has the characteristics of good directionality and high brightness. Its beam is concentrated in a very small emission angle along the axis (only about one-tenth of a degree). In addition, laser pointer Q-switching and other technologies can reduce the laser energy Compressed into a very narrow pulse (such as one trillionth of…

Why is the laser pointer display technology so hot?

In recent years, laser display technology has become the new favorite of projection companies and home appliance companies, including Hisense, Divi Video, Barco, Christie, NEC, Sony, LG, Changhong, Nuts, Guangfeng Optoelectronics, Simeile, Konka, etc. Leaders in the large-screen display industry have also established their presence in this field, and have continuously made breakthroughs, and the laser…

Israeli fiber laser pointer weapon technology attracts attention

A few days ago, the Chinese National Defense News published an article “Israeli Fiber laser pointer Weapon Technology Attention”, introducing the characteristics of Israel’s “iron beam” system in laser weapons. The content of the article is as follows: The “National Interest” website recently published an article entitled “The “Iron Beam” System: How Israel Use Lasers to Destroy…

Application of excimer laser pointer in glass

There is a new solution for this kind of laser pointer glass. The solid-state ultraviolet laser is also in the ultraviolet band. The substrate glass has very good penetration. The glass process that everyone needs in the OLED industry at this stage, high-power ultraviolet laser, we The ability to make high-power lasers is no longer a problem….

Laser energy-saving gun can directly output Chinese characters

This part is the result of new scientific research released last year and this year. In addition to the states on the previous page, this mode will also have more complex laser modes, which are actually different Hermitian Gaussian beams and Laguerre The complex superposition of Gaussian beams. On the left is the superposition state…

The results of the research team in the new laser pointer mode

After this, it was only in 2017 that they continued their work. In fact, their work was very similar. They also used the first-order Laguerre Gaussian beam to produce the same cone-shaped micro-nano structure, but their The structure is richer, they analyzed more parameters and more situations, and produced different results. The next job was…
