Laser engraving is a broad term which has various types. In order to choose the right form of laser engraving on your personalized gifts or trophies, it is important to know these differences. In this blog we will talk about the differences between two laser engraving techniques: CO2 laser engraving and fiber laser engraving.
Co2 laser engraving
As the name holds, Co2 lasers operate on carbon dioxide as an active medium. The lasers emit a set consistency of Co2 radiation at a preferred wavelength of around 10.6 micrometers. The process of co2 engraving involves a high voltage electrical discharge simulating gas molecules at an excited state. As these molecules are brought back to a lower state of energy, they emit photons of laser light. Co2 emits infrared radiation to absorb this wavelength effectively. This is why, co2 laser is best suited for engraving material such as wood, acrylic, paper and plastic.
Fiber Laser Engraving
In this type of laser engraving, optical fibers are combined with earthy elements such as erbium, ytterbium or neodymium as active mediums. A pump source, known as a laser diode pumps energy into the fiber to excite ions. This results in stimulated emissions generating lasers at a specific wavelength. Fiber lasers, however, emit visible and near laser spectrum at 10.5 micrometers. This shorter wavelength enables fiber lasers to have higher absorption rate on metals, making them a highly efficient option for engraving and marking.
Choosing The Right Form Of Laser Engraving in Houston For Your Personalized Needs
In this section, we will list down some of the fundamental differences between the two approaches of laser engraving discussed above.
- Co2 lasers are better suited for non-metal materials which fiber engraving can be used on metal.
- Fiber engraving is a high cutting and precise form which makes it an ideal choice for thin metals like sheet metal while co2 lasers can handle thicker materials.
- Fiber lasers are known for their high cutting speed which is why industrial applications are more inclined to this process. Co2 lasers, however versatile, may not cut as quickly as fiber lasers, which is why time presents itself as a constraint in the following type.
- If you have a highly intricate design in mind, fiber lasers can help you etch fine details on your said product in comparison to co2 lasers.
Having said that, it is also important to note that laser technology continually advances and each type has its set of unique strengths and limitations. In order to make the right decision, it is important to consult a laser engraving expert in Houston TX, who can provide valuable insights based on your product, volume and engraving needs.
