1.Small and compact size with common air-cooling system
2.Fiber output, flexible application, and easy construction of a 3D processing system
3.Backward reflecting isolator installed to block the laser reflected by work piece, preventing reflected light from reentering and damaging the laser oscillator
4.High beam quality and high reliability
Marking for various metal materials and part of non-metal materials. Suitable for processes requiring high marking depth, smoothness and accuracy.
