Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. It has the characteristics of small size and long lifespan...
In recent years, market demand has promoted the development of technology. Nowadays, when electronic products are becoming more and more refined, traditional soldering iron welding and wave soldering can no longer meet the welding of all electronic products.
Antibiotics is a major medical study in the 20th century. It is well known that excessive use of antibiotics can cause bacteria to develop resistance to drugs, which may make us repeatedly infected and life-threatening again.
Currently, stem cell therapy requires a large number of specific types of human cells. Recently, scientists have discovered through research that irradiating a near-infrared laser to adult stem cells derived from human fat can increase the replication speed of stem cells by 54%...
The laser used for measurement is much more accurate than a standard tape measure, and allows you to simply place and measure, rather than actually measuring the distance between points.
The utility model relates to the field of light quantum medical devices, in particular to a light quantum medical device adopting an incoherent monochromatic light source.
Shooting is a skill that makes perfect. One study found that regular shooters lose up to 20 percent of their skills after a week without training. The only way to prevent deterioration in shooting skills is through repeated practice, but expensive ammunition is a problem for shooters, and dry fire training is a great solution.
Cross line laser, and its structure consists of laser source, walk away, expanded beam collimation system and cylindrical lens, a single laser beam into the laser light off the piece...
However, for the processing of non-ferrous metals, especially copper, due to its low absorption rate of laser in the wavelength range of infrared light, the welding process is often unstable, and welding errors in production often lead to waste, so infrared light is not suitable for the welding of non-ferrous metals.
