Modern laser technologies used for cutting textile materials
With modern laser technologies we can cut multiple layers at once, yielding high production levels and short setup times between cutting runs. One example could be the operation of cutting the material named Nylon 66, used to manufacture automobile airbags. With laser, up to seven layers of Nylon 66 can be cut in one pass, that means high production rates on a single machine. Airbags must be precisely crafted piece of critical safety equipment that is built to very high levels of precision in a mass production environment. Of course, synthetic material, used for airbags, can be cut also by a conventional fixed blade system, but for a high production rates and a long term low-maintenance, la…
About some new possibilities of increasing the intrinsic output power of the photon beam: for definite laser active media
Producers and users of laser beam equipment have some wishes as: to have economic machines, the machines must be as small and light as possible, the power supply must be also very light and small. All mentioned desires - and other related with them - may be accomplished by an adequate efficiency of laser beam process. As we know, the first laser began with 2% efficiency. In the process of time, the efficiency increased progressive, and in this way was possible after the year 2000 to have laser weapons mounted on jet planes, including the power supply. In a laser system, there are many points where photons are lost. To reduce this losses, we must treat with the utmost care all points of the …
