Different laser techniques and why CO2 laser is optimal for wood

There are several different types of lasers used in the industry, but when it comes to engraving and cutting in wood, the CO2 laser the one that has traditionally been most popular. Let's take a closer look at why:

Different types of lasers

• CO2 laser : This type of laser uses a mixture of carbon dioxide, nitrogen and helium to generate the laser beam. CO2 lasers are very effective for cutting and engraving non-metals, including wood, plastic, fabric and paper.
• Fiber laser : Fiber lasers use an optical fiber to lead the laser beam. They are usually more powerful and have higher efficiency than CO2 lasers, making them excellent for engraving and marking of metals. What is a fiber laser and how is it used?
• UV laser: UV lasers use an ultraviolet laser beam and are very precise. They are often used in microelectronics and to create very fine structures.
• Dischases: Disk glaciums are a relatively new type of laser that uses a rotating disc as a laser medium. They are very powerful and are often used in industrial production.

Why CO2 laser is best for wood

• High absorption in wood: CO2 lasers have a wavelength that is very well absorbed by organic materials such as wood. This allows the laser to effectively extend the material and create pure cutters.
• Flexibility: CO2 lasers can be used for both cutting and engraving of wood, and can handle a variety of wood and thicknesses.
• Detail richness: CO2 lasers can create very detailed designs and engraving, making them ideal for artistic and creative projects.
• Cost efficiency: CO2 lasers have a good balance between performance and price, making them a popular choice for both small and large companies.

In summary, the CO2 laser is an excellent choice for engraving and cutting in wood due to its high absorption in organic materials, flexibility, detail and cost efficiency. Although other laser types such as fiber lasers can be used for some woodworking tasks, the CO2 laser is still the most popular and versatile solution for most wood work.

How Laser cuts and engraves wood: a physical explanation

When a laser hits wood, a fascinating physical process occurs that makes it possible to cut and engrave with high precision. Here is a simple explanation:

How it works:

1. The laser beam: A laser emits a concentrated light beam with a specific wavelength. For woodworking, CO2 lasers are often used, as their wavelength is well absorbed by organic materials such as wood.
2. Focusing: The laser beam is focused on a small point on the wood surface. The less focus, the higher the effect density.
3. Heating: When the laser beam hits the wood, the energy is transmitted from the light to the wood's molecules. This leads to a rapid heating of the wood that is hit by the laser.
4. Evaporation: When the temperature in the wood reaches a certain level, the material begins to evaporate. That is, the molecules of the wood are broken down and converted into gas.
5. Cutting or engraving:
   • Cutting: If the laser beam has a sufficiently high power, it will extend the wood completely through, which creates a clean and precise cutting.
   • Engraving: If the laser effect is lower, it will only vapor the top layer of the wood, which creates a darker surface and thus an engraving.

How different types of wood react to the laser beam

Different types of wood have different properties that affect how they react to the laser beam. Here are some examples of how hardness, porousness and color can affect the result:

Hardness

• Hard woods: Woods like oak, book and box are hard and dense. They often require higher laser effect and lower speed to cut through. The result is often clean and smooth cutters.
• Soft woods: Woods such as pine, spruce and pine are softer and easier to cut. They may require lower laser effect and higher speed. The risk of the wood igniting may be greater at too high power.

Porousness

• Porous woods: Wood with many pores, such as some deciduous trees, can provide a more uneven surface after laser treatment. This is because the laser beam can penetrate the pores and cause small charred particles.
• Dense wood: Wood with few pores often gives a smoother and smoother surface.

Color changes

• Color changes: When the wood is exposed to the laser beam, color changes may occur. This is because the lignin and tannins in the wood are broken down and oxidize.
• Darker color: Many types of wood get darker after laser treatment, especially on the cutters.
• Lighter color: Some types of wood may be lighter due to evaporation of moisture.

Other factors that affect the result:

• Moisture content: Moist wood is more sensitive to charcoal and can produce uneven results.
• The age of the wood: Older wood can be drier and harder, which can affect the cutting result.
• Laser settings: power, speed and focus affect how the wood reacts.

Examples of wood and their properties:

• Oak: Hard, dense, often gives a dark color change.
• Book: Hard, dense, provides a smooth surface.
• Pine: Soft, has clear annual rings, can give a yellowish tone after laser treatment.
• Mahogany: Hard, fine pore, gives a beautiful reddish brown color.
• Amber: Soft, light, can cause a dark brown color change.

To get the best results when laser -processing wood, it is important to:

• Choosing the right laser power and speed: Customize the settings to the wood and thickness of the material.
• Using the right focus: a correct focus provides the best possible harness quality.
• Test on a test piece: Always do a test on a small piece of the wood you should use to see how it reacts.

By understanding how different types of wood react to the laser beam, you can optimize your settings and get fantastic results.
