Compressed air cooling on laser tube mirror and windows; reduce high voltage shooting.

The beam quality is most close to TEM00; special metal coating are used on the electrode surface to significantly reduce electromagnetic sputtering and mirror contamination; using new cavity sealing technology.

The beam quality is close to TEM00; high voltage end uses molding ceramic cap; Standardized cathode processed by Japanese CNC machining center.

The process is mature and stable, the air tightness is high, and the beam quality is good; it is widely used in laser stamp carving, engraving, etc.
