Yongli A8s and H8 CO2 Laser Tubes have the maximum output power for the standard singular laser tube. With 150W to 180W output power, A8s and H8 are able to process a thicker level of organic materials at a relatively fast speed. 20mm Acrylic, for example, the speed is able to reach 2mm/s.
Despite A8s and H8, laser tubes sharing the same output power and length, there are also some differentiations between Yongli A8s and H8 CO2 Laser Tubes.
For the As series, raw glass materials are all from German Schott, and the discharge tube coating adopts the Island Structural Coating Techniques, therefore the stability and working lifespans have dramatic enhancement.
To get a better beam density, a unique resonator design is applied to As series CO2 Laser Tubes. Furthermore, in order to get high accuracy, all the resonator optical components are imported from II-VI Infrared Singapore. These are the reasons why A8s, 150W CO2 Laser Tube is capable of cutting thin steel and stainless steel.

Yongli As series CO2 glass laser tubes ranks at the top in nowadays CO2 laser market, for their Output power, Stability and Working Life.
Whereas, high performance requires high costs. To meet the Cost-effective enquiries from customers worldwide, in 2019, Yongli developed and fabricated H series CO2 laser tubes, which have similar beam quality and working stability to the As CO2 laser tubes. However, in order to deduct the manufacturing cost, we have to compromise on its working life span of it. If you are looking for a cost-effective and also bring you a fine laser cutting or engraving result. Yongli H series laser tubes are the best choice.

------------------------------------------
Acrylic:
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.
Die-board:
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.
MDF:
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.
Wood:
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:
Steel cutting will need Oxygen support during the cutting process. Air Pressure:0.8 MPa.
Paper:
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.
