It also has optimized features like water cooling and an air compressor, which not only means it works for longer, but it also means it’s safer and boasts the precision of up to 1/1000 of an inch.

Applications of CO 2 Lasers With 55W of power, the P2 surpasses even the 50W Gweike model and far exceeds the 45W Glowforge Pro. Its professional-grade 600mm/sec speed is twice as fast as the Glowforge Pro (around 300mm/s), and also faster than the OMTech Polar (500mm/s). This allows you to produce extremely accurate engravings of intricate and complex designs, such as photos, portraits, and other types of laser art. When testing the light spot on organic glass, please keep the organic glass 300mm away from the window.

So what is the warranty on a glass CO2 laser tube? This varies significantly between manufacturers, the diameter of the tube and the rated laser power. One constant is the warranty starts from the manufactured date, not from when it was first used. Typically the tube fails if it falls below 80% of the rated power within the warranty period. The CO 2 laser at the 9.25–9.6μm wavelength is sometimes used in dentistry for hard-tissue ablation. The hard-tissue is ablated at temperatures as high as 5,000°C, producing bright thermal radiation. [16] Other [ edit ] Radiation of the main mode is a process when a beam before going out of the resonator and becoming output radiation, runs exactly along the resonator axis (or parallel to it) and when reflected from a transparent and semitransparent mirrors gains power (amplifies) to pass a semitransparent mirror and exit the tube. In this scenario, it is the supplier that you need to consider carefully. Many people buy directly from China and unfortunately, there are already claims that the RECI tubes are being counterfeited. I have seen reports of people trying to buy EFR tubes and the Chinese supplier claiming there are production problems at EFR (there are not) and trying to push the probably counterfeited RECI tube instead. If you are going to buy your laser tube directly from a Chinese supplier, I would suggest taking the EFR product every time. 4. Correct Laser Power:Executing regular maintenance of your laser cutter goes a long way to extending the usable lifespan of your tubes, whether they are glass or metal. The one caveat many manufacturers will mention is to be careful when using hydrochloric acid with glass tubes because it could damage the glass. If your DC tube is really soiled with sediment, carefully flush it repeatedly with a diluted 3% or 5% HCL solution until it’s clean. Remember to also flush the cooling system, which will reduce sediment and residue deposits. With 90W power, it’s also significantly stronger than most hobbyist CO2 lasers. You can cut far deeper with this 90W CO2 laser in a single pass than with 40-60W lasers. From these data, we can conclude that the heat dissipation in the tube is somewhere around 330-350 watts.

A correctly rated laser tube (rated power not max power) will typically have around 10 ~ 15% more power than the actual rating, this additional power allows the manufacturers some headroom when it comes to warranty claims. So it’s not unusual for a 60-watt laser tube for example, to output 66 watts or more. What Is The Warranty On A Glass CO2 Laser Tube? WE WILL NOT BE A PARTY TO OR IN ANY WAY BE RESPONSIBLE FOR MONITORING ANY TRANSACTION BETWEEN YOU AND THIRD-PARTY PROVIDERS OF PRODUCTS OR SERVICES. Think about how much space you have in your workshop, what you want to sell or create for your business, and use this article to help find which laser is best suited for your specific needs!

The big draw for this machine, though, is its attachments. Water cooling, air compressors, fume extractors, rotaries, lenses, and tube upgrades effectively let you build this machine to your desired standards and allow you to maximize on versatility and efficiency. For example, the xTool P2 can support materials up to 118” long at a time if you have the conveyor feeder attachment, while the Glowforge Pro can support unlimited length. Although direct excitation of CO 2 molecules into the upper laser level is possible, it has proven to be most efficient to use a resonant energy transfer from nitrogen molecules. Here, nitrogen molecules are excited by the electric discharge into a metastable vibrational level and transfer their excitation energy to the CO 2 molecules when colliding with them. The exited CO 2 molecules then largely participate in the laser transition. Helium serves both to depopulate the lower laser level and to remove the heat. Other constituents such as hydrogen or water vapor can help (particularly in sealed-tube lasers) to reoxidize carbon monoxide (CO, formed in the discharge) to carbon dioxide. Figure1: Schematic setup of a sealed-tube carbon dioxide laser. The gas tube has Brewster windows and is water-cooled. Spectral Lines The main problem lies in the fact that in many cases the declared lifetime is much less in reality, or the power drops critically after the machine has been in use during 50-70% of the declared lifetime period.

Practical consequence of precision blanking wood:

Another OMTech model to consider is its new Polar 350. This machine is fairly different to other OMTech machines as the Polar 350 is a more modern and intuitive machine, with more quality-of-life features that make it easier to use. Because the excitation energy of molecular vibrational and rotational mode quantum states are low, the photons emitted due to transition between these quantum states have comparatively lower energy, and longer wavelength, than visible and near-infrared light. The 9–12μm wavelength of CO 2 lasers is useful because it falls into an important window for atmospheric transmission (up to 80% atmospheric transmission at this wavelength), and because many natural and synthetic materials have strong characteristic absorption in this range. [3] As expected at this price, the cutter comes with a removal bed, so it works on projects larger than itself, autofocusing, and has a unique 3D camera option that works with curved surfaces and uses millions of 3D data points to create accurate work.

Lett. 7 (1), 15 (1965); https://doi.org/10.1063/1.1754233 The CO 2 laser ( carbon dioxide laser) is a molecular gas laser with emission in the long-wavelength infrared spectral region. It is based on a gas mixture as the gain medium, which contains carbon dioxide (CO 2), helium (He), nitrogen (N 2), and possibly some hydrogen (H 2), oxygen (O 2), water vapor and/or xenon (Xe). Such a laser is electrically pumped via an electrical gas discharge, which can be operated with DC current, with AC current (e.g. 20–50kHz) or in the radio frequency (RF) domain.
