80W CO2 Laser Tube
Yongli A1s CO2 Laser Tubes employ the Islands Structural (Gold) Coating Technology onto the discharge tube to enhance Catalytic Ability, thus, significantly expanding the lifespan of the laser tube. H series CO2 glass tubes, on the other hand, adopt the chemical coating method to avoid the coating shedding issues and also increased the Catalytic Ability.

For the DIscharge Tube supplier -- the German Shott for all the glass raw materials of As series CO2 Laser Tubes, and the resonator inner lenses and mirrors are from US II-VI Infrared. The adoption of globally top-notch raw materials makes Yongli As series laser tubes perform extremely well on output power and stability

A1s and H1 CO2 Laser Tubes share many advantages in common, 

1. A-class glass supplier for The Discharge Tubes and Water-jacket Tubes: The German Schott. And both adopt the Chemical method to Discharge Coating.

2. Flange Design on the cathode end, to make sure every single laser tube reached its best beam quality that it could be reaching.

3. Metal Thermal Dissipation Cap allows Yongli 80W laser tube is capable of continuously working for a considerably long time.

4. High Stability, Yongli's unique producing techniques make the As and H series laser tubes contribute stable working status even during a long-time continuous working time.

However, there are also some differences between Yongli A1s and H1 CO2 Laser Tubes. For example, the working hours and outer diameters. Please check the reference table below for details.

To get a smooth and even acrylic cutting result, also avoid burnings. Please pay attention to the airflow control. Try to use small volume airflow on the surface of the acrylic or apply the side blow method, make sure there is also airflow at the bottom of the acrylic plate as well.


Focal length and Airflow are key factors for Die-board cutting. We suggest utilizing the focal lens with over 100mm focal length. Such a focus path will make the knife slit more precise.

A faster cutting speed requires greater airflow on the material surface. 
The smaller the nozzle mouth applied, the more cutting power you will get.


The faster-cutting speed requires greater airflow over the material surface. 

Leather & Fabric:

Laser power between 60W-100W is suggested and also equipped with a focal lens of 50 FL and a small power air compressor.


The faster-cutting speed requires greater airflow over the material surface.

PVC & Dual-color Board:

Laser power between 60-100W is suggested and also equipped with a focal lens of 50 FL and try to control the output power between 50%-70%.


Steel cutting will need Oxygen support during the cutting process. Air Pressure:0.8 MPa.


 Low laser power and fast speed for paper cutting are highly recommended. There is no perfect power and speed for multi-types of machines, get the correct power and speed on your test, please.

Artificial Rubber:

Normally, rubber cutting is a single-layer process, the reference we offered in this table is based on a double-layer cutting test.
