What Is The Best Laser Tube In China?

China is the biggest CO2 glass laser tube manufacturer in the world.It occupied the 90% market share around the world. More and more Chinese laser tube factories supply high-quality laser tube with a longer warranty, More and more laser dealers or laser machine end users all over the world are able to enjoy the benefit by Chinese laser tube manufacturing ability.it is a great improvement for laser equipment .such as 6040 co2 laser machine, 6090 laser co2 laser machines, 1390 laser machines ….In the meanwhile, we want to know who is the best co2 laser tube in china? We will give you a brief introduction of some famous manufacturers. I will recommend some famous brands in China to you.

Reci Laser tube 

Beijing Laser Technology Co. Ltd. Has officially launched W series and T series laser tubes. Reci upgrades and brings CO2 glass laser tube to 3.0 generation. Through the last ten years of development, the CO2 glass laser tube now develops to the third generation. The third generation of laser tube cancels the adjusting screws at both tube ends. Instead, the metal parts are made by high-precise CNC machines. New firing technology is used to join metal parts and glass parts together directly. 

Reci W series CO₂ laser tube has achieved three qualitative leaps after more than ten years of development. They have experienced the first generation of directly sticking the metal end with the lens to the glass tube mouth and cooling the light-emitting lens with water; the second generation adds adjustable screws on the two metal ends of the laser tube, thereby improving the installation accuracy of the laser tube and improving the product The qualification rate and output mode have increased by one level; the third-generation laser tube eliminates the adjustment screws at both ends, and adopts the process of direct sintering of the metal end and glass, which ensures the extremely high stability of the metal end structure without any changes in the mode.

How To Choose a Laser Tube ?

When you going to purchase the laser tube , you have to consider followed ideas for your reference:

1)Long Warranty:18Months.

We can tell you with certainty that we have a long warranty of 18 Months of Reci laser tube(Not all models),Others Usually only have 6 months or the longest 12 months.

2)Quality spare parts: Lens come from American II-VI , Bond with Kurt J.Lesker glue,Production process is GSI(GSI Lumonics Inc. to GSI Group Inc.),

Comparing those lenses of unknown quality and imitating the production technology without core, you will be more assured of the laser tubes.

3)Amazing power:Compared with the same model and the same size CO2 laser tube of other brands, reci power is often 10~20w higher than other brands. 

The most important thing is that this high power is continuous and stable.

4)Perfect Beam:Close to Model TEM00 profile,Beam quality(㎡)≤1.1

Regarding the beam,Almost all manufacturers and agents claim that their Beam mode is close to perfect TEM00, is it really true?Just test with thermal paper to see if your beam is round and has a balanced energy distribution.

5)After-sales service:Our after-sales team is very professional and has a wide range of knowledge reserves. 

They are not only familiar with CO2 laser tubes, but also familiar with machines, lenses, chillers, power supplies, and various circuit systems.

We can give you some professional suggestions of the laser field,such as mirrors for the machine, what chiller or power supply should be configured, etc. 

6)Competitive price:Excellent value for Cost.

Operating Tips

When using the laser tube, we should follow the following environment as far as possible to ensure that the service life of the laser tube can reach the longest.

Water cooling

  • Coolant: pure water
  • Flow rate: 3-5L/min.
  • Standard water temperature: 10℃ -40℃

Working environment

  • Temperature: 2℃-40℃
  • Humidity: 10%-60%

Operating current

  • The CO2 laser tube requires an input current of 25mA, a maximum operating current of 25mA and a current of 23mA and below for long-term operation. If the operating current is kept at 23mA or below, the service life is up to 3,000 hours. These currents should be based on the currents displayed on the ammeter, which is in a series connection with the cathode.

Cleaning Tips

Please do not use cotton swabs or other wipes to scrub the windows on this laser equipment spare part. Doing so affects the output power.

The specified cleaning method for the windows is as follows

1. When the lens is stained, turn off the laser tube.

2. Use an air dust blower to blow away dust and dirt on the lens.

3. Use a syringe to spray ethanol on the lens.

4. After the ethanol evaporates, turn the laser tube back on.

5. If the above methods do not work effectively, professionals are required, who will use a cotton swab dipped in ethanol to clean the lens in a rotating fashion away from the center, outwards to the edge.

The best method is to protect the windows from contamination.

Special Notice

1. Do not use acetone to clean the glass.

2. When testing the light spot on organic glass, please keep the organic glass 300mm away from the windows.

Safety: As the CO2 glass laser device generates invisible light, please wear eye protection gear when operating. A safety sign for high voltage is marked on the positive pole.

Storage and Transportation Requirements: When storing and transporting the CO2 laser tube, please drain the cooling liquid and cover the tube ends with dust proof plastic bags. For storage, the required environmental temperature is 2-40°C and the humidity ranges from 10-60%.

Adhesive tapes and sponges should be used to fix the laser tubes and prevent sliding during transport. A 70mm sponge should be used at the end of the windows, and a 50mm sponge should be at the end of the fully reflecting mirror.
