What Is Laser Ablation?
By focusing a laser on the substrate of the material, we are able to accurately remove material on the surface without harming the material underneath. The process can be controlled by raising or lowering the laser’s pulse length, wavelength and intensity.
Laser ablation is essential for manufacturing specific parts that require a non-traditional processing method, such as nanomaterials and superconducting materials. In order to remove material from the surface without changing the structure or causing damage when producing these products, it’s imperative to use the laser ablation technique. The energy from the laser is absorbed and is transferred throughout the material, and then breaks down the chemical bond.
The benefits of laser ablation lie in its accuracy and its versatility. This form of technology can be used on a variety of materials like plastic, metal and ceramic. The laser can be directed on a minuscule area if needed, because it is accurate at machining down to a single micron.
Our team of experts will test your materials to find the right combination of wavelength, beam quality, pulse repetition and rate to get the desired results that you need. Laser ablation is an environmentally friendly process, which means that we can apply the laser ablation process to almost any material without causing harm.
The technique of laser ablation is not only used to remove materials like silver chloride, gold and thin film or plastics. It is also used to determine the chemical levels and concentration on a surface, or it can be used to place film for processing nanomaterials.
Laser ablation is the wave of the future for high-tech production needs. With a wide variety of applications in many different industries, laser ablation may be the solution you’re looking for.
Optimize an amazingly versatile process with our expertise.
Laser ablation can meet your needs when conventional manufacturing methods can’t, putting a wide range of specialized micromanufacturing goals within reach. Laser Light Technologies will help you fine-tune from start to finish.
Laser Light’s custom ablation processes selectively remove layers of substrate or coating from the surface of manufactured parts, having little to no effect on other areas. Common coating removals include parylene, polyamides, silver chloride and gold, but many others are possible. It’s also possible to target minute areas or create patterns, and ablation is suitable for a wide variety of substrate materials including glass, ceramics, metals and semiconductors.
Our approach to ablation starts with a test of your material sample, to evaluate removal efficiency and establish parameters for laser micromanufacturing and post-laser processing. This allows us to make recommendations for optimal quality, efficiency and productivity. It also enables us to provide you with the most accurate project quote possible.
Laser ablation offers a level of controlled depth and micron-level precision unmatched by any other manufacturing method. If you don’t see your specific need in the list here, please contact us to start a conversation about our capabilities and your options.
