100W CO2 Laser Tube

Yongli A4s and H4 both adopt the German Shott Discharge tube. A4s employs the Islands Structural (Gold) Coating Technology to enhance Catalytic Ability, thus, the lifespan of the laser tube is expanded significantly. H series adopts the chemical coating method to avoid the coating shedding issues and also increased the Catalytic Ability.
All the glass raw materials of As series Co2 Laser Tubes are supplied by German Schott, and the 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 excellently on output power and stability.

The discharge tube quality is one of the key factors that affect the lifespan and stability of CO2 Laser Tubes. In order to increase its quality of it, we chose the global leading glass supplier, German Schott, for our 3rd generation of CO2 Laser Tubes. Chasing for further optimization, Yongli enhanced the mode of the As series. And both adopt the Chemical method of Discharge Coating.


Metal Thermal Dissipation Cap allows As and H series CO2 laser tubes to be capable of continuously working for a considerably long time.

Yongli's unique producing techniques make the As and H series laser tubes contribute stable working status even during a long-time and continue laser processing job.

100W CO2 Laser Tubes A4s and H4 are mostly applied to the laser cutting process, yet, due to the excellent beam quality and an OK response time, sometimes it is also been used for laser engravings.

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.

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.
