As one of the most important scientific and technological inventions of mankind in the 20th century, the laser diode has directly promoted the development of a number of emerging disciplines and high-tech skills, such as nonlinear optics, laser spectroscopy, strong field physics, optical communicati......

What is the difference between ordinary light-emitting diodes and laser diodes?

Like laser products, whether in traditional industries or all walks of life, in our lives, red laser module guided missiles and other red laser module weapons, or newly developed red laser modules destroy drones, satellites, etc., in many ways, red laser modules Are inseparable.

According to a recent report on the official website of Nagoya University in Japan, researchers at the school said that they have designed a laser diode that emits the shortest wavelength of ultraviolet light so far, which is expected to be used in disinfection, dermatology and DNA analysis.

A group of scientists from the Hong Kong University of science and technology, the University of California Santa Barbara, Sandia National Laboratory and Harvard University were able to directly manufacture micro lasers on silicon, which became a huge breakthrough in the semiconductor industry.

The simplest distinction is that infrared laser diodes are invisible light, and red laser diodes are visible light.
