Recently, research teams from Sandia National Laboratories and the University of Toronto made groundbreaking breakthroughs in miniature terahertz sources, and succeeded in increasing the power output of terahertz lasers by 80%. It is expected that in industry Imaging and chemical detection and other fields have been widely used.
The project is now favored by NASA to measure oxygen content to explore interstellar media components.
Due to the terahertz laser source emitting laser light in the opposite direction, resulting in its actual output efficiency is low, at least half of the energy was wasted, making the application is limited.
In order to solve this problem, the research team adopted a new structural design. The use of quantum cascade laser to form a "standing wave" and to add cracks in the standing wave, making the terahertz laser can burst out of the waveguide, and coincide with the opposite direction of the band to increase the laser intensity. The device successfully led 80% of the laser intensity in the right direction. At the same time, the design also solves the problem of laser synthetic loss caused by traditional mirrors and is very important for improving the efficiency of the terahertz laser.
This design is used to further increase the power of the THz laser, but some of it is still wasted. The future also need to improve the overall performance of the laser beam, resulting in higher quality laser beam.
The blades of scrap crushers use refined alloy knives with super hardness. The meshing blade forms a pair of rollers, and when the material enters the crusher, the opposite movement of the rollers is carried out together to tear up the scrap. With regard to the material that cannot be torn up, the scrap will not be knocked dead. it will carry out an intelligent rotation, spit out the material that is difficult to swallow, and then break it from the head until the scrap is broken into small blocks, which can be discharged from the outlet to stop.
When the material enters the crushing bin, the scrap crushing opportunity intelligently shred from the simplest part of the material, easy first, then difficult, and so on, until the material is completely shredded and stopped. Scrap broken from small to large, there are many types, different types of blades equipped with different diameters, generally speaking, as long as the material scale does not exceed the size of the cutter box, can be easily broken, to ensure the output together, but also to ensure quality.
