Fiber Laser Applications: Laser Ablation
Our latest Application Overview focuses on Layer Ablation, a process which our Pulsed Fiber Lasers can be used for in order to remove surface layers from substrates without causing any damage.
Over recent months we have highlighted five laser industrial manufacturing challenges that can be simplified using an SPI Fiber Laser, including Cleaning, Marking, Additive Manufacturing, and Engraving. Each month we summarise the details of the application and identify the benefits of using a fiber laser to provide a faster, more efficient and cost effective solution for mass processing on an Industrial level.

We take a closer look into Layer Ablation this month, finding out what it is, how it works, and what are its main benefits to Industrial Manufacturing?
Layer Ablation: An Introduction
Our redENERGY Pulsed Fiber Laser range are the ideal tools to undertake layer ablation, as it is extremely versatile and is able to remove a wide range of coatings. This has proven beneficial for many businesses, for example, within the Electronics industries, where the process is used to remove the insulating layer from electrical wires, in order to repair, replace, or re-connect a wire.
Another example is where our Pulsed lasers can be used to etch bright metals from ceramics to expose the non conductive layer underneath. Users can quickly and cleanly create electrical isolation using this process, which can then be used for electrical circuitry.
Although layer ablation can be applied to a variety of materials such as metals and ceramics, high quality can only be achieved with the correct parameters, as materials react differently to the intensity of a Fiber Laser. Learn how our Pulsed Fiber Lasers can be adjusted to meet an abundance of applications and give the best results by visiting our redENERGY G4 Pulsed Laser Page.
How Layer Ablation Works
There are several steps to Layer Ablation, from the initial point where the beam meets the surface layer, to where the entire layer has been removed.
For layer ablation to happen, the beam must be focussed on the surface, and also have the correct pulse parameters.
The pulse energy is absorbed leading to surface heating of the layer. Soon after the layer starts to melt, it quickly vapourises, and starts to evaporate.
The rapid expansion causes a recoil pressure wave which ejects molten material. The ablation process comprises of two material removal mechanisms, evaporation and melt ejection.
What are the advantages?
Layer ablation is a targeted process which removes layers of coating from a substrate. Our user-friendly redENERGY Pulsed Fiber Lasers are highly-flexible giving you control over applications to achieve precision results every time.
End-users can adjust pulse conditions to work with different surface layers and successfully remove them from the substrate.
Another advantage of layer ablation using Pulsed Fiber Lasers is quicker processing speeds. Once the material has absorbed the Pulse, the layer is heated rapidly which forces a chain reaction to occur rapidly, resulting in greater throughput and productivity. See how our redENERGY Pulsed Fiber Lasers can be used to improve your business’s productivity and profitability on our G4 Homepage.
Users may also benefit from a non-consumable process, due to no chemicals being used to melt or evaporate layers from the substrate. In the long term, this can prove far more cost-effective than conventional methods, as it removes the need to replace the source chemicals, and consequently provides an environmentally-friendly solution to implement into your business.
