Unlike standard glass-head tubes that are prone to cracking and gas leakage, this laser tube features an upgraded metal head. This design significantly improves heat dissipation and structural integrity, protecting the critical electrode seals.
Whether you are upgrading a machine or replacing a worn out tube in a professional engraver, this laser source delivers the precision spot size needed for detailed engraving.
STABLE POWER OUTPUT: The optical cavity is designed to produce a high-quality TEM00 beam mode that results in a smaller focal spot for finer engraving details and cleaner cutting edges.
EXTENDED SERVICE LIFE: Features an advanced nano-catalyst coating inside the discharge tube. This helps regenerate the CO2 gas mixture during operation, significantly extending the working life of the tube compared to standard models.


WIDE MATERIAL COMPATIBILITY: Perfect for cutting up to 3-5mm plywood/acrylic and engraving on coated metals, glass, leather, paper, and fabric.
SECURE CONNECTION: The metal head allows for a more secure high-voltage wire connection, reducing the chance of arcing and simplifying the installation process.
