Judging from the current development of laser weapons, the Navy may become the first service to deploy laser pointer weapons among the three services. This is not only because the Navy has been advancing the development of laser weapons for a long ti ...
Usually, the focus lens is glued to prevent displacement. So you can't turn around. There is scattered light, noise, it is estimated that the lens is stuck by dust, please clean it. They got stuck and couldn't turn, but when I turned on the laser poi ...
Laser diodes are not as complicated as many types of consumer electronic devices. It is composed of laser pointer diode, circuit board, housing, optics and housing. Certain electronic components and laser diodes on circuit boards are made of semic ...
Townes had predicted that the device’s radiation had extraordinary and useful properties: it would be at a single frequency, as pure as the notes from a tuning fork. That's it. The highly ordered nature of this radiation will make laser masers an ...
In 2020, the laser pointer will celebrate its 60th anniversary. Here, the photonics media presents a timeline of some of the more famous scientific achievements related to the optical amplification of stimulated emission (laser). An interactive ve ...
Did you know that the term "laser pointer" is an acronym for "light amplification caused by stimulated emission of radiation"? Consumer laser pointers cannot pierce steel or destroy robots, but they can help you circle the main points and guid ...
Scientists boast that radar has won the war, and the atomic bomb has ended the war. What will physicists create next? As the Cold War against the Soviet Union progressed, the US government invested more and more funds in basic and applied research ...
By the beginning of the 20th century, scientists realized that light can be viewed as electromagnetic waves, similar to laser pointer waves, but with a much shorter wavelength. The spectrogram shows various forms of electromagnetic radiation. The ...
Since ancient times, people have believed that light carries a huge and mysterious power. With the discovery of radio, laser pointer and radioactivity, interest in radiation began to double in the early 20th century. The entire spectrum of radiati ...
Semiconductor lasers are also called laser pointer diodes (LD). With the development of semiconductor physics, people imagined the invention of semiconductor lasers as early as the 1950s. The semiconductor laser in the early 1960s was a homogeneo ...
Semiconductor laser pointer is a device that generates laser light by using a certain semiconductor material as a working substance. Semiconductor lasers realize non-equilibrium carriers between the energy bands of semiconductor materials (conduct ...
It refers to a laser pointer with a single laser function. No matter whether the pen can write or stretch to become a pointer, it always takes the function of the laser as the main body, and the price ranges from ten yuan to tens of yuan. This typ ...
Over the years, the quality of Laser pointer has been greatly improved. The cost of ownership and required maintenance costs have been reduced. But laser is more than just light. The system that generates the beam is still made of physical matter. ...
In order to understand the transmitted light beam, the technician uses a beam profiler using a camera, Laser pointer or non-contact Rayleigh scattering. These are NIST traceable devices that can measure power density curves according to known standar ...
