Infrared light-emitting diodes (IR leds) and laser pointer diodes (LD) are not new technologies. They were invented in the 1960s. Recently, however, solid state lighting (SSL) has grown rapidly. LED and LD were originally developed for optical communication applications, but now they are widely used in data communication/telecommunications, consumer electronics, automotive and industrial fields to…

Femtosecond laser-induced shape memory polymers
Recently, the school of engineering sciences, university of science and technology of China (ustc) has made a new breakthrough in femtosecond laser pointer-induced material processing. The institute, in collaboration with the national university of Singapore, used femtosecond lasers to fabricate reconfigurable structures on the surface of shape memory polymers, discovered a new “polymer self-growth” effect,…
The smallest 10,000-watt fiber laser
“This innovative 10,000-watt laser will bring the smallest volume in the industry and the highest output power in the industry,” said Jake Bell, general manager of enner’s global industrial lasers division. “Its combination of size and power not only enables end users to achieve more space savings for the overall system, but also gives it…

In August this year, liu lingling, deputy secretary of the party committee and director of urology department of the fourth affiliated hospital of China medical university, brought green laser pointer surgery equipment…
Development status and future trend of ultrafast laser
In recent years, with the continuous upgrading of technology and the change of market demand, laser technology has been applied more and more in the fields of consumer electronics, new display, laser internal carving, biological medicine and other fields, and these new requirements have become more demanding on the precision of laser pointerprocessing. Stimulated by…
Assisted laser communication Switzerland is working on a technique for lasers to penetrate clouds
Recently, foreign media reported that in order to better carry out laser communication, Switzerland is studying how to let the laser through the cloud technology. Laser communication is a way to transmit information by laser. The laser communication system consists of two parts: sending and receiving. The sending part mainly includes laser, light modulator and…
The us Marine corps is developing a new laser weapon that can transmit voice messages remotely
The us Marine corps is developing a new laser weapon that can transmit voice messages remotely, deafen, blind or burn the recipient, foreign media reported. The “scalable compact ultra-short pulse laser system” (SCUPLS) will be a “non-lethal” crowd-control weapon. The intense pulses emitted by the ignition laser pointer last only a few millionths of a…
Us researchers study new laser weapon: near area makes pain worse
Military forces in many countries are actively researching laser weapons, and the United States is no exception. According to CNET, the new laser pointer weapon being developed by the us Marine corps is not a powerful and lethal weapon, but rather a warning to the enemy. Specifically, the laser weapon system can be to warn…
Scientists used lasers to create temperatures of 20 million degrees Celsius
Scientists at the SLAC national accelerator laboratory in California have created conditions inside stars and planets on earth that reach 20 million degrees Celsius, 4.3 million degrees Celsius hotter than the center of the sun, foreign media reported. SLAC, part of the U.S. department of energy, has the world’s longest linear particle accelerator. When the…
Four main features of laser weapons
Laser weapon is a kind of directional energy weapon, which USES high energy concentrated laser pointer beam to directly damage or disable the target. High-intensity laser beams can be used to destroy or kill enemy aircraft, missiles, satellites and personnel. Strong laser weapons have incomparable advantages over other weapons, such as fast speed, high precision,…
