YN Diode side-pump laser marking machine is the new product developed by YuanNuo factory, which is updated product of YAG laser marking machine. It adopts the most advanced laser technology in the world and the imported diode laser arrays. The 808nm laser diode pumping Nd: YAG mediums produce quantity of antiparticles, which will cause 1064nm high power laser pulse output under the function of Q switch. The beam quality is very good and the line is rather nice. For the convenience of our customers, we have improved the machine structure. The optical system uses the fully sealed structure. Anyway, it is easy to operate and protect the laser system well. Not only can it work alone, but also cooperate with other equipments in production line.
