FUZHOU XK PHOTONICS CO., LTD was established in 2009, at the beginning, we worked on Green laser core (Nd:YVO4 and KTP crystal), which can emit 532nm with pumping by 808nm LD at huge Q'ty. Now, we focus in: optics components for RGB,including: Cylindrical lens, mirror, PBS plate or cube, quartz crystal 90deg rotator or waveplate, also, we can provide diffusion bonding prism for RGB ouput. Also, we can provide lens for 3-14um application with single point diamond lathe. And we can provide TGG crystal, TeO2 crystal, KTP crystal for different application.We are now following the fast developping of LD laser application, and manufacture the corresponding lens, components.
