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 ...

More importantly, for the purposes of this guide, portable Laser pointer technology has become more and more popular because you can now use battery-powered lasers with multiple wavelengths and power outputs that were unimaginable a few years ago. ...

One measurement in the process can provide complete process measurement and analysis. The beam is led to the analysis system, which usually consists of a power measurement system, a beam profile analysis system and a time pulse shape measurement syst ...
