YongLi T4 Premium Laser Tube 50W, 55mm Dia, 850mm Length

T4 45–50W, 850mm, 55mm diameter CO2 laser tube offering exceptional pulse capability, outstanding beam quality, and ultra-fast response for high-demand engraving and marking applications.

The Yongli T4 is the most powerful member of the T series family, building on the proven platform established by the T0 and T2. Rated at 45–50W and measuring 850mm in length with a 55mm outer diameter, it inherits the same hallmark traits of the series while stepping up output for more demanding applications.
Like its siblings, the T4 combines the reliable output of traditional tube design with modern flange cathode construction and advanced chemical coating techniques. The T series' standout strength lies in its exceptional pulse capability — a result of carefully tuned tube length and gas ratio — delivering outstanding beam quality, ultra-fast response times, and effortless alignment via an integrated red dot pointer.
Whether driving high-throughput desktop engravers or high-speed marking systems, the T4 offers the performance headroom to handle heavier workloads without compromising on the precision and consistency the T series is known for.
