Laser pointers or laser flashlights have been around for more than 30 years. In recent years, some child abuse, laser pointer events caused personal injury accident, mainly is the eye, because our eyes curious about new things to compare, this caused the attention of academia and ophthalmic community. Because of the intense focus of the laser, the power to transmit the power, and the result of the warming, it can cause the retinal burn, causing the eyesight to drop. It's even blind.
He knew that it was forbidden to take photos in the concert hall, which was a reminder to him to collect his cell phone, but he felt the opportunity was rare, and he insisted on taking photos. For the sake of "rare opportunity", he took photos of the violation, and when the staff of the concert hall photographed him with a laser pointer, he felt aggrieved that he was impolite and arrogant. How should you remind someone who has violated the rules? Is there a better way?
In early September, the wuhan evening news reported, Mr. Tao in qintai concert hall to watch mobile phones take pictures during the concert, there are staff with a laser pen to exposure to remind him, he questioned: "this way of reminding, will some arrogant, rude?"
China weather news: global warming, less sea ice, more extreme weather, more air pollution... Climate change, environmental change and human activities on the climate, environment and ecology, the negative effect is becoming the major problems affecting the sustainable development of human society, actively respond to climate change has become a global consensus.
Huainan, anhui, Sept. 10 (xinhua) -- China's national institute of atmospheric physics (APSOS), a research group led by the Chinese academy of atmospheric sciences, said on Monday that it had received unanimous approval from Chinese experts on the "multi-band multi-atmospheric composition of the main passive integrated detection system" (APSOS).
Do you believe that an ordinary laser pen can travel 100 miles in the air? We did it, and I believe you can do it.
The manufacturer Tangram Design Lab has launched an iPhone Smart Dot style laser pen, which is a special app for iOS, and this laser pen will make it easy for you to demonstrate on the iPhone, where you go to the big conference room or the podium, where you're going, where to point it. The laser pointer is very convenient to carry and first when not in use, the user can put it in a protective sleeve cap type, and the protective cap itself or a touch pen, can be used to touch on the iOS device.

Scientists at Aston university show the world's longest lasers.The non-destructive transmission of optical communication signals with wavelength of 1550nm was realized by using this 75km fiber laser cavity.
In the long distance fiber-optic link, the distributed amplification can make up for the attenuation of the signal in the transmission process.In order to achieve nearly lossless transmission in optical fiber, the scientists used various methods to make along the optical fiber transmission for gain, and realize the amplified spontaneous emission (ASE) noise control.The Aston team has provided a solution by using the transmission optical fiber as a Raman laser, achieving a near-lossless transmission and minimizing the ASE noise.
