In 1640, a Jesuit priest named Atanas Koscher who was born in Gesha, Germany, invented a slide projector called the “magic” lamp, which was the first projector in the world. After three and a half centuries, EIKI produced the world’s first 16mm film projector in 1953, SHARP launched the world’s first single-chip LCD video projector…

Superimpose the laser pointer beam on the target aiming point
The two technologies achieve accumulation and enhancement of laser energy. Most traditional laser pointer weapon test systems use a large laser to emit laser light, while the “iron beam” laser weapon system uses a three-stage stacking method of beams to achieve cumulative enhancement of laser energy. That is, a stack of multiple tiny lasers is combined first,…
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….
Bending the laser pointer beam to transmit information to create a world record
Scientists at the University of Vienna succeeded in encrypting the bending laser beam and allowed the bending laser pointer beam to travel up to 143 kilometers. This travel record set a new world record, almost 50 times higher than the previous record. This new breakthrough may bring revolutionary changes to satellite communication methods. Light is an electromagnetic…
Some optical components that regulate the laser pointer
Then, like the curve on the right like a positive rotating wave, in fact, one cycle of the laser field itself oscillates in the cavity is a laser pointer wavelength, so there may be many laser wavelength values in the cavity. Then this is called the longitudinal mode of the laser, because it is along the cavity…
The spatial structure of the interactive forming laser pointer
These applications in various aspects, this is a simple example. We are laser additive manufacturing, here is also the meaning of it. In our additive manufacturing or laser pointer-based additive manufacturing, we first build a two-dimensional structure, and then continue from two-dimensional to three-dimensional process. In fact, this process can be referred to as laser 3D…
Test laser pointer to realize laser communication
“80 satellites carrying IoT communications will be launched by 2023 to achieve global coverage.” On the 24th, the fourth “China Space Day” series of events were held at Wuhan National Aerospace Industry Base, Deputy General Manager of Aerospace Cloud Technology Co., Ltd. Du Li said that Xingyun Project will launch two test satellites, Xingyun II…
New progress has been made in module research Laser pointer
The research group of the Thin Film Optics Technology Research Office of the Institute of Optoelectronics Technology of the Chinese Academy of Sciences has made new progress in the study of laser pointer pulse width broadening technology in excimer lithography systems: a pulse width broadening structure based on a double beam splitter and multiple mirrors is proposed….
Semiconductor laser pumped solid-state laser pointer
Pulsed nanosecond laser is one of the main products. This series has a very wide product line, with power ranging from tens of watts to 2500 watts, and peak power from KW to MW. The largest application market for nanosecond laser pointer is the cutting of battery tabs, whether it is power batteries, 3C soft pack batteries,…
Two laser pointers are electronically controlled in space and time
In an electron microscope, electrons are excited by sharp metal tips, so they can be manipulated and controlled with high precision. Recently, such a metal tip is also used as a high-precision electron source for generating X-rays. A team of researchers from the Vienna University of Technology (Vienna), in collaboration with researchers from the University…
